Process for the preparation of substances with ester, amide, urea and urethane groups |
| abstract |
Process for the preparation of substances with ester, amide, urea and urethane groups with elimination of CO 2 by reaction of A) carboxylic acids, B) alcohols and C) isocyanates in the presence of heteroaromatic amines at a reaction temperature below 100 ° C for the start of the CO 2 elimination reaction, wherein one equivalent of isocyanate 0.1 to 5 equivalents of a mixture of carboxylic acid and alcohol and 0.0001 to 0.5 equivalents of amine come, wherein the ratio of alcohol: acid 10: 1 to 1: 10 and being used as heteroaromatic amines 4-amino-substituted pyridines and / or N-substituted imidazoles. |
