Abstract

Petroleum fractions are treated at elevated temperature with sulphur or a sulphur compound which liberates sulphur at the temperature used, in the presence of a nitrogen-containing rubber vulcanization accelerator. The sulphur reacts with olefins present giving a product of reduced tendency to gum. If desired, this may be separated by distillation from the complex sulphur compounds formed. Where sulphur is present as such or as disulphides, e.g. in cracked stocks, further addition of sulphur may be unnecessary. The vulcanization accelerators include nitrogen bases and their derivatives, condensation products of aldehydes with ammonia or amines, guanidines, especially aryl guanidines, and compounds containing sulphur, e.g. thioureas, dithiocarbamates, mercaptothiazoles, mercaptobenzthiazoles, and thiuram disulphides. Specific examples are zinc dimethyl (or dibutyl) dithiocarbamate, piperidine pentamethylene dithiocarbamate, and mercaptobenzthiazole. Temperature is generally 50-400, preferably 125-175 or 200-300 DEG C., using free or combined sulphur respectively. The amount of accelerator is generally up to 10 per cent. by weight of the sulphur. In an example, a reformed naphtha is refluxed with 1 per cent. of sulphur and .01 per cent. of mercaptobenzthiazole at 165 DEG C. for 7 hours. Specification 696,439, [Group IV (b)], is referred to.
