ω sulfonation, diazo coupling, hydrolysis and salting out. 以邻氨基苯甲醚、间氨基苯磺酸和甲醛为起始原料,经ω磺化、重氮偶合反应,最后通过水解、盐析得染料中间体4 -氨基-3- 甲氧基苯基偶氮苯-3’- 磺酸钠。2) post-azo-coupling 后重氮偶合 1. Poly(N-vinyl carbazole)containing(p-nitrophenyl) azo...
There is some nonspecific staining with the diazo-coupling technique but not with the formazan and silver staining techniques. The differences, in the mobility of the liver, bone, and intestinal isoenzymes achieved by homogeneous-pore gel electrophoresis are sufficient to allow them to be clearly ...
Diazo-coupling reactions of the pendant aniline residue were examined with phenol and resorcinol, and the formation of desired polymers was confirmed by comparing the structures between the polymer products and the authentic polymers by IR and 1 H-NMR spectroscopy....
