Appropriate aromatic amines were diazotized and coupled with the active methylene of the PVK to give a group of yellow pigments, which have the similar properties with Hansan Yellow dye. 然后再以合适的芳胺经重氮化反应偶合到PVK的活性亚甲基上,合成出类汉沙黄颜料。
The coupling reaction of α-naphthol with diazotized sulphanilic acid was used as a working reaction system for checking the effectiveness of the dual-sphere model in a stirred batch reactor. 用α-萘酚与对氨基苯磺酸重氮盐在稀水溶液中的偶合反应作为工作反应物系,在间歇釜式搅拌反应器中实验,以检验双球混和模型。
This paper studies the coupling reaction method of dyeing the wool, i. e. the diazotized wool coupling with Naphtol and the pretreated wool coupling with the diazotized base. 本文探讨了羊毛偶合反应染色新方法,即重氮化羊毛与色酚的偶合染色以及预处理羊毛与重氮化色基的偶合染色。
Preparation of Ternary Copolymer Diazotized Latex and Its Application 三元共聚重氮胶乳的研制及其应用
CL was diazotized to be conjugated with BSA and OVA to prepare artificial antigens II ( CL-BSA) and coating antigen II ( CL-OVA). 采用重氮化法将CL直接与BSA、OVA共价偶联,制备人工抗原Ⅱ(CLBSA)和包被原Ⅱ(CLOVA)。
