Abstract

307,813. Carpmael, A., (7 G. Farbenin. dustrie Akt.-Ges.). Dec. 13, 1927. 1 : 4: 5-Trimethoxyanthraquinone is obtained by treating 1: 4: 5-trihydroxyanthraquinone with p-toluenesulphonic acid methyl ester in nitrobenzene solution in presence of sodium carbonate. It dyes cellulose acetate greenish-yellow shades of good fastness.
