Some common aliphatic solvents are Mineral Spirits, petroleum naphtha, petroleum distillate, cyclohexane, octane, pentane or isopentane nonane. Many solvents can contain a blend of different aliphatic types or aliphatic and aromatic hydrocarbons depending on the end use. Hydrocarbons may contain traces or larger amounts of aromatic compounds and the higher the aromatic content the better the Kb or solvency. Petroleum hydrocarbons are available in two grades, the basic petroleum distillates and the specialty grade of synthetic paraffinic hydrocarbons.
These are technologically less advanced, as they contain components that have a broad range of boiling points and may include trace amounts of benzene derivatives and other aromatics. Petroleum distillates were available many years before such solvents as low VOC hydrocarbons, Odorless Solvents, and chlorinated solvents attained their popularity.
More recently, improved separation and synthesis techniques have led to the production of the specialty grade of paraffinic hydrocarbons. Compared to petroleum distillates, the paraffinic hydrocarbons have very low aromatic content, narrower boiling ranges, and higher solvency. Plus they are more expensive. So typical of these later solvents are the Isopars, the Linpars and Exxsol solvents — all of which CCC offers in our complete line of solvents.
They are typically used when water contact with the parts is undesirable. Cleaning with petroleum distillates lends itself to simple, inexpensive, one-step cleaning in situations where a high level of cleanliness is not essential. In addition, they have low liqui d surface tension which allows them to penetrate and clean small spaces. Some precision cleaning operations are most effective with hydrocarbon cleaners.
No water is used with hydrocarbon cleaners and therefore, there is no potential for water corrosion or for water to become trapped in cavities. The primary pollution prevention benefits of petroleum hydrocarbon solvents are that they produce no wastewater and that they are recyclable by distillation.
Paraffinic grades have very low odor and aromatic content and low evaporative loss rates. However, planned recovery of VOCs is an important part of pollution prevention if these solvents are to be used.
They are successfully used in packaging, end use, BBQ Fluid, general cleanerspaint and coatings as thinnersink as thinnersand machined automotive parts as a degreaser. As one of the top chemical suppliers in Canada, CCC has extensive technical expertise and a wide selection of hydrocarbon solvents and petroleum hydrocarbon solvents.
A blog of the American Chemistry Council: driving innovation, creating jobs, and enhancing safety. This Web site deals with a subset of "organic" solvents, specifically hydrocarbon and oxygenated solvents. For example, water is a solvent, but is "inorganic," so is not discussed here. Oxygenated and hydrocarbon solvents represent most of the total organic solvents used each year in the United States.
Organic solvents can be classified by chemical structure. There are three main types:. Those solvents are typically of a high purity with specifications ranging from Specifications for these solvents typically focus on impurities, such as water and non-volatile matter.
The impurities present in these solvents are normally well characterized and can be predicted from the chemistry involved in their manufacture. Typical specification properties include distillation range, flash point, density, aromatic content, and color.
Information on halogenated solvents is at the Halogenated Solvents Industry Alliance Web site, and is not discussed on this site. View our resource center to find press releases, testimonies, infographics and more.

Jobs The business of chemistry providesskilled, good-paying American jobs.Many different solvents are used in a wide variety of everyday product applications — from paint, personal care products and pharmaceuticals, to pesticides, cleaners and inks.
Without solvents, many products we rely on would not perform as well. Types of Solvents: The chemical classification of a solvent is based on its chemical structure. For manufacturers, solvents are subject to a variety of federal and state regulations, including regulations that govern the industrial storage and disposal of hazardous wastes, workplace exposure limits, requirements for safe transport of chemical substances, and regulations pertaining to release of chemicals to air, land and water.
Federal agencies including the U. Hydrocarbon and oxygenated solvents have been in widespread use for more than 50 years and the subject of extensive health and environmental effects studies that examine the effects of exposure to solvent vapors.
It should be noted that in some cases, people use solvents directly e. Various solvents are extremely effective in select purposes, such as in pharmaceutical development. In producing penicillin, for example, the solvent keeps the impurities in the solution so the penicillin is selectively removed from the reaction mixture by extraction.
In some inks, the solvent effectively evaporates quickly enough to prevent smudging and provides a cost-effective, high performing way to print magazines or labels using vivid colors. In nail polish, the purpose of the solvent is to dissolve and help mix the other ingredients together evenly, and then evaporate as the nail polish dries, creating a smooth, consistent surface.
Fingernail polish remover also is a solvent that functions for this particular use — to break down the ingredients in the polish. In chemistry, solvents — which are generally in liquid form — are used to dissolve, suspend or extract other materials, usually without chemically changing either the solvents or the other materials. Organic solvents are carbon-based solvents i. Many different classes of chemicals can be used as organic solvents, including aliphatic hydrocarbons, aromatic hydrocarbons, amines, esters, ethers, ketones, and nitrated or chlorinated hydrocarbons.
Some of the most common uses of organic solvents include chemical synthesis, clothing dry cleaning, paint thinners, nail polish and glue removers as well as detergents. These type of cleaning solvents are used to remove oil, grease, solder flux used to make electronics and other contaminants. Home improvement products, such as paints, finishes or glues, may also contain solvents to help them perform effectively.
Solvents Industry Group. European Solvents Industry Group. Halogenated Solvents Industry Alliance.In organic chemistrya hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.
Hydrocarbons from which one hydrogen atom has been removed are functional groups called hydrocarbyls. Aromatic hydrocarbons arenesalkanescycloalkanes and alkyne -based compounds are different types of hydrocarbons. Most hydrocarbons found on Earth naturally occur in petroleumwhere decomposed organic matter provides an abundance of carbon and hydrogen which, when bonded, can catenate to form seemingly limitless chains.
Hydrocarbons can be gases e.Using maths to predict football
Because of differences in molecular structure, the empirical formula remains different between hydrocarbons; in linear or "straight-run" alkanes, alkenes and alkynes, the amount of bonded hydrogen lessens in alkenes and alkynes due to the "self-bonding" or catenation of carbon preventing entire saturation of the hydrocarbon by the formation of double or triple bonds.
This inherent ability of hydrocarbons to bond to themselves is known as catenationand allows hydrocarbons to form more complex molecules, such as cyclohexaneand in rarer cases, arenes such as benzene. Generally, with catenation comes the loss of the total amount of bonded hydrocarbons and an increase in the amount of energy required for bond cleavage due to strain exerted upon the molecule; in molecules such as cyclohexane, this is referred to as ring strainand occurs due to the "destabilized" spatial electron configuration of the atom.
In simple chemistry, as per valence bond theorythe carbon atom must follow the 4-hydrogen rule, which states that the maximum number of atoms available to bond with carbon is equal to the number of electrons that are attracted into the outer shell of carbon.Empty row in table html
In terms of shells, carbon consists of an incomplete outer shell, which comprises 4 electrons, and thus has 4 electrons available for covalent or dative bonding. Hydrocarbons are hydrophobic like lipids. Some hydrocarbons also are abundant in the solar system.
Lakes of liquid methane and ethane have been found on TitanSaturn 's largest moon, confirmed by the Cassini-Huygens Mission. Hydrocarbons are a primary energy source for current civilizations. The predominant use of hydrocarbons is as a combustible fuel source.
In their solid form, hydrocarbons take the form of asphalt bitumen. Mixtures of volatile hydrocarbons are now used in preference to the chlorofluorocarbons as a propellant for aerosol spraysdue to chlorofluorocarbons' impact on the ozone layer. Methane CH 4 and ethane C 2 H 6 are gaseous at ambient temperatures and cannot be readily liquefied by pressure alone. Propane C 3 H 8 is however easily liquefied, and exists in 'propane bottles' mostly as a liquid.
Butane C 4 H 10 is so easily liquefied that it provides a safe, volatile fuel for small pocket lighters.
Pentane C 5 H 12 is a colorless liquid at room temperature, commonly used in chemistry and industry as a powerful nearly odorless solvent of waxes and high molecular weight organic compounds, including greases. Hexane C 6 H 14 is also a widely used non-polar, non-aromatic solvent, as well as a significant fraction of common gasoline.
The C 6 through C 10 alkanes, alkenes and isomeric cycloalkanes are the top components of gasolinenaphthajet fuel and specialized industrial solvent mixtures. With the progressive addition of carbon units, the simple non-ring structured hydrocarbons have higher viscositieslubricating indices, boiling points, solidification temperatures, and deeper color. At the opposite extreme from methane lie the heavy tars that remain as the lowest fraction in a crude oil refining retort. They are collected and widely utilized as roofing compounds, pavement composition, wood preservatives the creosote series and as extremely high viscosity shear-resisting liquids.
Hydrocarbon use is also prevalent in nature. Some eusocial arthropods, such as the Brazilian stingless bee, Schwarziana quadripunctatause unique hydrocarbon "scents" in order to determine kin from non-kin. The chemical hydrocarbon composition varies between age, sex, nest location, and hierarchal position. Hydrocarbon poisoning such as that of benzene and petroleum usually occurs accidentally by inhalation or ingestion of these cytotoxic chemical compounds.Hexane Extraction Hexane is a clear, colourless liquid with a faint odour.
It is a stable paraffinic hydrocarbon which is highly volatile and distils over a very narrow range.√ Physical Properties of Hydrocarbons - Energy - Chemistry

Rubber and related industries such as adhesives are typical end uses for this solvent. It consists essentially of the ortho, meta, para xylene isomers and ethylbenzene.Hydrocarbon solvent substances are commonly derived from petroleum feedstocks and contain one or more hydrocarbon classes e.
The difference between the types of hydrocarbon solvents is mainly due to their different hydrocarbon classes and their carbon chain length distribution. The carbon chain length distribution depends on the targeted distillation range of the final product. The hydrocarbon solvent carbon chain lengths are typically narrow cuts of hydrocarbon lengths over C5 and below C Due to the variability in the composition of the starting materials, many hydrocarbon solvents fall under the definition of a UVCB substance.
The major process for transforming petroleum feedstocks into hydrocarbon solvent substances is a combination of various process steps that may include distillation of the feedstock, hydrodesulphurisation, mild or heavy hydrogenation, and finally a distillation and a stripping of light components.
Uh oh! You're not signed up. Close navigation. Popular Terms.
