碱性绿-4的合成及性能

Synthesis and performances of alkali green-4

报道了合成碱性绿 -4的最佳条件 :在醋酸介质中 ,尿素、氯化锌为催化剂 ,四氯苯醌和重铬酸钾为氧化剂 ;对该染料性能进行测试 :配伍值为 3 ,湿摩擦牢度 4～ 5级 ,干摩擦牢度 5级 ,皂洗牢度 5级 ,沾色牢度5级 .

The optimal conditions for synthesis of alkali green 4 are reported,including the carbamide and zinc chloride as catalyst,chloranil and bichrome as oxidation agent in the acetic acid medium.The performances of dye were tested and the results are compatibility number 3,wet rub strength 4～5,dry rub strength 5,soaping firming number 5,and transfer of colour number 5.
