本文对乙烯砜型染料的七个模拟物分离条件进行了研究,优选了离子对试剂的品种、用量及冲洗剂甲醇/水的组成。在甲醇/水(35/65—50/50) 中,加入0.01mol/L 四丁基碘化铵(TBAI),可以将4-(β-羟基-,4-(β-硫酸酯-,4-(β-磷酸酯-,4-[β-(N-甲基-β′-磺基乙胺基-,4-[β-(N,N-2乙胺基-和4-(β-(氯乙基砜基)苯胺以及4-乙烯砜基苯胺很好地分开。对KN型活性染料模拟物4-(β-硫酸酯乙基砜基)苯胺在90℃不同pH下水解反应动力学进行了研究。实验表明,不同条件下反应进行的程度差别较大。
In this paper, the separation conditions of seven mimics of vinylsulfone dyestuff were studied, and the species and amount of ion-pair reagent and the composition of rinse methanol / water were optimized. A solution of 4- (β-hydroxy-, 4- (β-sulfate-, 4 - (β-phosphate-, 4- [β- (N-methyl-β’-sulfoethylamino-, 4- [β- (N, N-2 ethylamino- and 4- (β- (Chloroethylsulfone) aniline and 4-vinylsulfonanilide.The kinetics of hydrolysis reaction of 4- (β-sulfatthylsulfone) aniline of KN type reactive dye at different pH at 90 ℃ The experiments show that the reaction under different conditions vary greatly in degree.
