(57) [Summary] [Structure] The present invention provides a method for producing an amide derivative of an acid by reacting a haloaminotriazine with an acid halide. The present invention also provides a method of preparing isocyanates and isocyanate adducts from amide derivatives derived from haloaminotriazines and acid halides such as oxalyl chloride, phosgene and phosgene analogs. By reacting trichloro and hexachloromelamines with chloroformic acids and acid chlorides, Produce melamine-derived acid amides. This by-product chlorine can be reused in this way. By the novel method of the present invention, it is possible to produce amides, carbamates, sulfonamides, phosphoramides and related amide derivatives. |
