Synthesis method of biochemical preparation TMB
-
Paragraph 0043-0045, (2018/03/26)
The invention discloses a synthesis method of a biochemical preparation TMB. The synthesis method includes following steps: synthesizing 1,2, 2', 6, 6'-azo tetratoluidine-N, N-dioxide; synthesizing 1,2, 2', 6, 6'-tetramethyl diphenylhydrazine; synthesizing 3,TMB (1/2)H2SO4; preparing 4,TMB 2HCl; preparing TMB. The synthesis method is simple in synthesis route, cheap and easy-to-obtain in raw material, low in synthesis cost and high in yield.

A number of chloro-, methyl- and methoxy-substituted azobenzenes have been reduced to the corresponding hydrazines by using an aqueous solution of Na 2S2O4. The yield is generally excellent, but two compounds, viz. 4,4-dimethoxyazobenzene and 2,2,4,4,6,6- hexamethylazobenzene, gave no hydrazine at all. Georg Thieme Verlag Stuttgart.
