Abstract

1309903 Monoazo dyes; fuel additive WILLIAMS (HOUNSLOW) Ltd 22 April 1970 [22 April 1969] 20507/69 Headings C4P and C5G [Also in Divisions C3 and D1] The invention comprises hydrocarbon-soluble dyes, or mixtures thereof of formula wherein R is H or C 2 H 5 , the rings A and B may be further substituted other than by watersolubilizing groups, there being an average of 1À5 to 4 C 2 H 5 groups per molecule present as R radicals or as ring substituents in A or B. The dyes are prepared by azo coupling using appropriate components or by treating an appropriate diamino-azobenzene with an ethylating agent, e.g. diethyl sulphate. The dyes are soluble in solvents such as benzene, toluene or xylene to give 60% w./w. pourable concentrates (see Division D1B) which are used to colour liquid fuels and polystyrene granules (see Division C3) in yellow shades.
