Abstract: Formic acid is recovered, by distillation, from its mixtures with solvents of the general formula I where R1 is hydrogen, methyl, ethyl or vinyl and R2 and R3 are each alkyl, cycloalkyl, aryl or aralkyl, or R2 and R3 together form a 1,4- or 1,5-alkylene group of 1 to 8 carbon atoms, with the provisos that the sum of the number of carbon atoms in R2 and R3 is 7 to 14 and that only one of these radicals is aryl, by a method in which the distillation is carried out in the presence of a carboxamide II which has a boiling point lower than that of the solvent I.

Abstract: A process for the production of propionic acid which comprises the reaction of ethylene with carbon monoxide and water in the presence of a nickel carbonyl complex at a temperature of from 250 DEG to 320 DEG C in the liquid phase and at a pressure of from 100 to 300 atmospheres in a vertical cylindrical reaction zone, a gaseous zone being maintained at the upper end of the reaction zone and a bottom zone being maintained at the lower end of the reaction zone which is not in communication with said reaction zone over the entire cross section.
