METHOD FOR SEPARATING HIGH-BOILING CARBOXYLIC ACID VINYL ESTER/CARBOXYLIC ACID MIXTURES |
| 摘要 |
The invention relates to a method for separating a mixture containing at least one carboxylic acid vinyl ester of general formula R′—C(O)O—CH═CH2 and at least one carboxylic acid of general formula R′—COOH, wherein R′ in either case can be an aliphatic group having 12 to 22 C atoms or a cycloaliphatic group having 12 to 22 C atoms, or an aromatic group having 12 to 22 C atoms, and R′ can be identical or different, characterized in that the carboxylic acid is converted to its anhydride R′—C(O)—O—C(O)—R′ and the carboxylic acid vinyl ester is subsequently separated. |

1. A process for separating a mixture comprising at least one vinyl carboxylate ester of general formula R′—C(O)O—CH═CH2 and at least one carboxylic acid of general formula R′—COOH, wherein in each case R′ may be an aliphatic radical having 12 to 22 carbon atoms or a cycloaliphatic radical having 12 to 22 carbon atoms or an aromatic radical having 12 to 22 carbon atoms and R′ may be identical or different, said process comprising the steps of converting the carboxylic acid into its anhydride R′—C(O)—O—C(O)—R′ and subsequently removing the vinyl carboxylate ester. |
