PROCESS FOR THE MANUFACTURING OF ORGANIC POLYCARBOXYLIC ACIDS |
| abstract |
Process implementing a functional exchange reaction. It comprises: 1. Heating to a temperature of at least 100 degrees C, in the presence of water, a mixture comprising a first organic imide and a first organic anhydride, or its polycarboxylic acid precursor, for a period of time sufficient to effect an imide-anhydride functional exchange to produce a mixture comprising a second organic imide and a second polycarboxylic acid or the corresponding anhydride; 2. Separation of the second organic imide or of the second polycarboxylic acid or anhydride from the mixture of 1. Application to the manufacture of plasticizers. |
