| Use | used as scorch retarder for natural rubber and synthetic rubber (except butyl rubber), it can also be used as a re-plasticizer of the compound that has been slightly scorched, and can also be used as a high-efficiency polymerization inhibitor. Industrial use as a scorch inhibitor for natural rubber and synthetic rubber (except butyl rubber), it can also be used as a re-plasticizer for compounds that have been slightly scorched. It can replace wood tar as high efficient anionic polymerization agent of chloroprene rubber. It is an intermediate of antioxidant 4010 and dye. |
| production method | is obtained by reacting diphenylamine with sodium nitrite in the presence of sulfuric acid. Nitrosation reaction with ethanol or xylene (or chlorobenzene) as solvent, sodium nitrite solution concentration of 40%. The concentration of sulfuric acid was 30%, and the reaction was carried out at about 26 ° C. For 2.5-3H. The reaction was washed with water to pH = 6-7. When the ethanol solvent is used, the solid product N-nitrosodiphenylamine is obtained after drying; When xylene or chlorobenzene is used as the solvent, the liquid product is obtained, and the liquid product is obtained after drying with calcium chloride. |
