EXAMPLE 2 Ethyl difluoroacetate (20 g 0.161 mol) is brought together with formic acid (7.4 g, 0.161 mol, 1 equivalent) and 0.1 g of 98% by weight sulfuric acid in a glass reactor surmounted by a distillation column. The reaction medium is brought to the temperature of 70° C. at atmospheric pressure and a distillation fraction is then collected, so as to keep the temperature at the column top constant at 55° C. A fraction of 12 g of ethyl formate is obtained.
