2-[2-chloro-4-[3-chloro-4-[2-oxo-1-(phenylcarbamoyl)propyl]azo-phenyl]phenyl]azo-3-oxo-N-phenyl-butanamide - Production method
After diazotization of 3,3 '-dichlorobenzidine, it is coupled with acetanilide, and then the product is prepared by filtration, drying and other processing processes. 1. Diazotization 2. The coupling product requires the color light to be similar to the standard product, the tinting power is the standard product 100±5 (points), the moisture content is less than or equal to 2%, the oil absorption is 50±5%, the water-soluble salt content is less than or equal to 1.5%, the heat resistance is 180 ℃, the sun resistance is 5-6, the acid resistance and alkali resistance are all 1-2, the water permeability and oil permeability are, fineness (content of residue through 60 sieve) ≤ 5%. Raw material consumption (kg/t)3,3 '-dichlorobenzidine (100%) 410 acetanilide (100%) 590 hydrochloric acid (31%) 930 sodium nitrite (industrial) 235 soda ash (industrial) 495 glacial acetic acid 615 activated carbon 10 Taikao oil 55 Method 2: Starting from o-nitrochlorobenzene, it is reduced with zinc powder in caustic soda solution medium and condensed to 2,2'-dichlorodiphenylhydra. Then it is treated with hydrochloric acid. Translated to 3,3 'dichlorobenzidine hydrochloride. Then the 3,3 '-dichlorobenzidine is diazotized, and then coupled with o-acetyltoluidine to obtain the product. 1. Reductive condensation 2. Translocation, salting out 3. Diazotization, coupling
