HARNESS PLUS(R) - Preparation Method
Open Data Verified Data
2.6 monoethyl monochloroacetoaniline was obtained from the reaction of 2,6 monoethyl aniline with chloroacetic acid and phosphorus trichloride. Ethanol reacts with Polyoxymethylene in the presence of hydrochloric acid to produce chloromethyl ethyl ether. Acetochlor is then formed from the condensation of 2,6 monoethyl monochloroacetoaniline with chloromethyl ethyl ether.

| Production method | 2, 6-methylethylaniline reacts with chloroacetic acid and phosphorus trichloride to produce 2, 6-methylethyl-chloroacetoaniline; Ethanol reacts with polyoxymethylene in the presence of hydrochloric acid, and after etherification, chloromethyl ethyl ether is obtained; finally 2-methyl-6-ethylchloroacetoaniline and chloromethyl ethyl ether undergo condensation reaction, acetochlor is produced. The emulsifiable concentrate 50% the product is light brown yellow liquid; 43% emulsifiable concentrate is reddish brown liquid. Raw material consumption quota: 2-methyl -6-ethylaniline 600kg/t, chloroacetic acid 480kg/t, ethanol 250kg/t, polyoxymethylene 150kg/t, caustic soda 1100kg/t. 2, 6-methylethylheptaamine reacts with chloroacetic acid and phosphorus trichloride to produce 2, 6-methylethyl-2-chloroacetoanilide. Ethanol reacts with polyoxymethylene in the presence of hydrochloric acid to produce chloromethyl ethyl ether. 2, 6-Methylethyl-2-chloroacetoaniline is condensed with chloromethyl ether to produce acetochlor. |
