PROCESS FOR PREPARING DIKETONES AND KETO-ACIDS |
摘要 |
This invention concerns a process for preparing diketones and keto-acids by reacting a dicarboxylic acid and an aromatic compound in the presence of an alkylsulfonic acid such as methanesulfonic acid and an organic anhydride compound such as methanesulfonic anhydride or trifluoroacetic anhydride. The diketones and keto-acids can be used to prepare polyketones which are useful as molding plastics, coatings, films, fibers, and the like.
