Abstract

Aromatic hydrocarbons are purified by contact with sulphuric acid containing dissolved alkali metal bisulphate. The hydrocarbon may be benzene, toluene, benzole or detergent alkylate, e.g. C9-C18-alkyl benzene or toluene. The sulphuric acid, of 90-100% by weight concentration, is used in amounts of 0.5-5 volumes per volume of hydrocarbon and should contain insufficient bisulphate, e.g. of sodium or potassium, to cause separation of solids, usually less than 50 moles per 100 moles of acid. The temperature may be 20 DEG -100 DEG C.
