摘要

This invention provides a process for preparing amide derivatives of acids by the reaction of haloaminotriazines and acid halides.;This invention also provides a process for preparing isocyanates and isocyanate adducts from amide derivatives derived from haloaminotriazines and acid halides such as oxalyl chloride, phosgene and phosgene analogs.;Melamine derived acid amides are prepared by reaction of trichloro and hexachloromelamines with chloroformates and acid chlorides. The by-product chlorine may be recycled in this process.;Amides, carbamates, sulfonamides, phosphoramides, and related amide derivatives may be prepared by the novel processes of the invention.
