Abstract

Low-boiling hydrocarbons are prevented from gumming by adding both a colourless inhibitor and an inhibitor which is a dye; inhibition is therefore effective at least as long as the liquids are coloured. The inhibitor may be added as a solution in benzene or other solvent. Colourless inhibitors specified are a -naphthol, secondary amyl p-amino-phenol, hexyl-p-phenylene diamine, methyl-aniline, toluidine, aniline, phenol, o, m, p cresol, tricresol, and anthraquinone. For example, gasolene may be treated with 0,010 per cent of a -naphthol and 0,001 per cent of the blue indophenol formed by the condensation of a - or b -naphthol with p-nitroso-dimethyl aniline; or with 0,020 per cent of tricresol and 0,003 per cent of the red indophenol obtained by condensing diphenylamine with p-nitroso-phenol. Specification 385,066 is referred to.
