2,5-二甲氧基苯胺 用途与合成方法


化学性质  灰色片状固体。 溶于水、乙醇、热里格罗因。


用途  用于制备冰染染料黑色盐K的中间体及医药、杀虫剂和抗氧剂的中间体


用途  该品用作染料中间体,用来生产黑色盐K(C.I.37910)。这个染料品种主要用于拼混黑色盐AMS。该品也用于生产药物、农药和抗氧剂等。


用途  有机合成,染料中间体,杀虫剂,抗氧剂。


生产方法  对苯二酚溶解在液碱中生成对苯二酚钠盐。将对苯二酚钠盐和一氯甲烷在75-120℃、1.3-1.7MPa压力下反应生成对二甲氧基苯,再用硝酸硝化,生成2,5-二甲氧基硝基苯,用二硫化钠将其还原,即得2,5-二甲氧基苯胺。
