Process for producing carboxylic acid esters, and "onium" salts and salt mixtures thereof |
| abstract |
(57) An improved method for producing a carboxylic acid ester from an alcohol and a carboxylic acid, a carboxylic acid chloride, or a carboxylic acid bromide. SOLUTION: The corresponding carboxylic acid and 1,5-diaza- Bicyclo [4.3.0] -non-2-ene ("DB N ") or 1,8-diaza-bicyclo [5.4.0] Operating in the presence of an adduct ("onium" salt) with undec-7-ene ("DBU"), or "Onium" by operating in the presence of the corresponding carboxylic acid and the "onium" salt of the corresponding carboxylic acid The esterification is performed while avoiding salt precipitation. |
