Process for the preparation of alpha-chloroacetoacetic-acid monomethyl amide |
| abstract |
In the manufacture of a-chloroacetoacetic acid monomethylamide by the action of chlorine on acetoacetic acid monomethylamide in an aqueous medium at temperatures from - 20 to + 10 ° C in the presence of urea and alkali salts, neutralization of the reaction mixture, separation of solid a-chloroacetoacetic acid monomethylamide and recycling of the mother liquor to the next Batch yield and purity of the product are improved by extracting the mother liquor obtained after the separation of a-chloroacetoacetic acid monomethylamide before returning it to the next batch with an inert, water-immiscible solvent.n n n a-Chloroacetoacetic acid monomethylamide is a valuable intermediate for the production of insecticidal active ingredients. |
