Treatment of 1 mol 4-AcNHC6H4SO2CH2CH2OH at 80-130≦̸C with 2.4-3.8 mol concd. H2SO4 gives a mixt. of 4-H2NC6H4SO2CH2CH2OSO3H and 4-H2NC6H4SO2CH2CH2OAc which, when diazotized and coupled with 1,8,3,6-HO(H2N)C10H4(SO3H)2 (I), form a mixture of dyes II (R,R1 = SO2CH2CH2OAc, SO2CH2CH2OSO3H, SO2CH:CH2; at least one of R and R1 = SO2CH2CH2OAc) and III (R2,R3 = SO2CH2CH2OSO3H, SO2CH:CH2, SO2CH2CH2OH; at least one of R2 and R3 = SO2CH2CH2OSO3H or SO2CH:CH2). The mixt. dyes cellulosic material fast black shades and shows better solyl., depth of shade, and build-up than dyes of structure III obtained by coupling I with the difficulty prepd. 4-H2NC6H4SO2CH2CH2OSO3H.
