is a compound with a strong capability to dissolve a
given substance. The most common petroleum
solvents are mineral spirits,
xylene, toluene,
hexane, heptane,
and naphthas. Aromatic-type
solvents have the highest solvency for organic chemical materials, followed
by naphthenes and
paraffins. In most applications the solvent disappears, usually by
evaporation, after it has served its purpose. The evaporation rate of a
solvent is very important in manufacture: rubber cements often require a
fast-drying solvent, whereas rubber goods that must remain tacky during
processing require a slower-drying solvent. Solvents have a wide variety of
industrial applications, including the manufacture of paints, inks, cleaning
products, adhesives, and petrochemicals.
Other types of solvents have important applications in
refining.
