Abstract
A catalytic distillation process reacting in a column bottom was experimentally studied for the transesterification of methyl and ethyl esters of bromodifluoroacetic acid with trifluoroacetic acid. Sulfuric acid was used as a catalyst. Experiments were performed at different column bottom heat duties. As a result of the experiments, we had bromodifluoroacetic acid with a purity above 97.0 mol % at a product yield of 87.4%.
