PVC may be manufactured from either naphtha or ethylene feedstock. Aromatics are produced by catalytic reforming of naphtha. It is mainly converted in naphtha reformers to toluene. The hydrocarbons used are sometimes made by hydrogenation from naphtha. TAME derives from C5 distillation fractions of naphtha. The fuel is also known as petroleum naphtha. The two main solvents for rubber are turpentine and naphtha (petroleum). Reactive finishes may use solvents such as white spirits and naphtha as a base. Flambeaux are powered by naphtha, a highly flammable aromatic. The biorefinery producing renewable diesel and naphtha started operating in Lappeenranta in 2015. Giovanni Fabbroni is credited with the discovery of naphtha as a rubber solvent in 1779. The remainder are products ranging from tar to naphtha. Cyclopentene is produced industrially in large amounts by steam cracking of naphtha. Lithium is safely stored in non-reactive compounds such as naphtha. Mineral spirits, also historically known as "naphtha", are not the same chemical.
