The term "petroleum solvent" describes special liquid hydrocarbon fractions obtained from naphtha and used in industrial processes and formulations. These fractions are also referred to as "industrial naphtha".
"Naphtha" is a liquid petroleum product that boils from about 30°C (86°F) to approximately 200°C (392°F), although there are different grades of naphtha within this extensive boiling range that have different boiling ranges. The term "petroleum solvent" is often used synonymously with "naphtha".
On a chemical basis, naphtha is difficult to define precisely because it can contain varying amounts of its constituents (paraffins, naphthenes, aromatics, and olefins) in different proportions, in addition to the potential isomers of the paraffins that exist in the naphtha boiling range. Naphtha is also represented as having a boiling range and carbon number similar to those of gasoline, being a precursor to gasoline.
Here are three kinds of solvents:
