Method of purifying and separating 2-fluoro-3-oxoalkylcarboxylic acid ester |
| abstract |
The present invention concerns a method for purifying/separating a 2-fluoro-3-oxoalkylcarboxylic acid ester from a reaction mixture resulting from the fluorination of a 3-oxoalkylcarboxylic acid ester. The method involves depleting the reaction mixture of a hydrogen fluoride byproduct; and subsequently, separating the 2-fluoro-3-oxoalkylcarboxylic acid ester by distillation. The 2-fluoro-3-oxoalkylcarboxylic acid ester obtained by the method of the invention is highly pure and is thus suitable for use as an intermediate for the production of pharmacological products or agricultural chemicals. |
