| 摘要 | 285,641. British Celanese, Ltd., and Olpin, H. C. Feb. 9, 1927. Samples furnished. Anthraquinone derivatives.-Sulphuric esters of anthraquinonylamino alcohols, which are dyestuffs for organic substitution products of cellulose, e.g. cellulose esters and ethers, and for animal fibres, are made by treating the corresponding alcohols with sulphuric acid or oleum; or by the action of sulphuric esters of aminoalcohols on leuco oxyanthraquinones, e.g. the leuco compounds of 1-oxy-, 1 : 4-dioxy-, 1 : 4 : 5- trioxy or 1 : 4 : 5 : 8-tetraoxy-anthraquinone, followed by oxidation of the leuco body; or by replacement of chlor, nitro, methoxy &c. groups by treatment with sulphuric esters of aminoalcohols, e.g. #-aminoethyl alcohol. The anthraquinonylamino alcohols, for treatment with sulphuric acid or oleum, may be obtained by treating amino or mono-substituted amino derivatives of anthraquinone or substituted anthraquinones with halohydrins, e.g. ethylene, propylene or glyceryl chlorhydrins, epichlorhydrin, or chlorbutylene glycol, or with alkylene oxides, e.g. ethylene or propylene oxide, or with oxyaldehydes or ketones, or by replacement of chlor, nitro, hydroxy, methoxy &c. groups by treatment with an amino alcohol. The sulphuric esters of 1-#-oxyethylamino-, 1-#-oxyethylamino-2 (and 4)- methyl-, 1-#-oxyethylamino-4-oxy (and amino)-, 1-#-oxyethylamino-2-brom-4-amino-, and 1 : 4- and 1: 5-di-#-oxyethylamino-anthraquinones are specified. | ||||||
