S02：基底合成：硫酸和亚硝酰硫酸混合，控制温度在20-30℃，同时加入2,6-二溴-4-硝基苯胺，加完后，保持反应温度20-30℃，反应至终点，得到重氮盐；
偶合组分用水和硫酸溶解，降温至0℃，加入重氮盐进行偶合，终点后升温至60℃，在60℃时过滤水洗，得到基底；
S03：产物合成：二甲基乙酰胺和基底混合升温至70℃溶解，加入氰化锌、硫酸铜，升温至110℃，保持反应温度110℃，反应至终点，降温至30-40℃加入水，搅拌至结晶析出，过滤得粗品；往粗品中加入水、三氯化铁，升温至60℃，加入盐酸，盐酸加入过程中保持反应温度60℃，加完后保持60℃的温度进行反应，最后过滤水洗至中性，得到产物。

S02：基底合成：硫酸和亚硝酰硫酸混合，控制温度在20-30℃，同时加入2,6-二溴-4-硝基苯胺，加完后，保持反应温度20-30℃，反应至终点，得到重氮盐；偶合组分用水和硫酸溶解，降温至0℃，加入重氮盐进行偶合，终点后升温至60℃，在60℃时过滤水洗，得到基底；
S03：产物合成：二甲基乙酰胺和基底混合升温至70℃溶解，加入氰化锌、硫酸铜，升温至110℃，保持反应温度110℃，反应至终点，降温至30-40℃加入水，搅拌至结晶析出，过滤得粗品；往粗品中加入水、三氯化铁，升温至60℃，加入盐酸，盐酸加入过程中保持反应温度60℃，加完后保持60℃的温度进行反应，最后过滤水洗至中性，得到产物。
7.一种如权利要求1-6任意一项所述的一种分散兰染料的应用，其特征在于，所述的分散兰染料应用于疏水性纤维或纤维的混纺物的染色。
