Abstract

Sulphur compounds are removed from benzol and other light oils by treatment at 30-90 DEG C. with sulphuric acid of 60 to 85 per cent strength, as by boiling the oil with acid of 73-82 per cent strength, or by passing the oil vapour through acid of 70 per cent strength at 84 DEG C. In an example 500 gallons motor benzol are agitated with 50 gallons acid of 82 per cent strength for about 2 hours at 83 DEG C. in a sulphonator fitted with a reflux condenser, and the purified benzole separated by distillation or gravity.
