4-Amino-3-methyl-N-ethyl-N-(.beta.-hydroxyethyl)-aniline sulfate which is used particularly as a developer for color photography can be easily produced in high yield and high quality by nitrosating N-ethyl-N-(.beta.-hydroxyethyl)-m-toluidine by use of an alkyl nitrite in a homogeneous alcohol solution containing sulfuric acid in an amount of about 0.5 to about 1 mole per mole of N-ethyl-N-(.beta.-hydroxyethyl)-m-toluidine, and then reducing the nitrosation product in an aqueous alcohol solution after or without isolation of the nitrosation product.

氨基-3-甲基-N-乙基-N-(β-羟乙基)-
苯胺硫酸盐是一种用于彩色摄影的显影剂,可通过在含有
硫酸约0.5至1摩尔/摩尔N-乙基-N-(β-羟乙基)-间甲
苯胺的均相醇溶液中使用烷基
亚硝酸盐来硝化N-乙基-N-(β-羟乙基)-间甲
苯胺,然后在分离或不分离硝化产物的情况下,在
水醇溶液中还原硝化产物,从而可以轻松高产高质量地生产。
