Abstract: A PROCESS FOR THE PRODUCTION OF METHYL FORMATE FROM ALKALI OR ALKALINE EARTH FORMATE BY REACTION WITH AT LEAST AN EQUIVALENT QUANTITY OF METHANOL AND STRONG ACID IN THE PRESENCE OF SUFFICIENT WATER TO KEEP THE REACTANT FORMATE IN SOLUTION, FOLLOWED BY DISTILLATION OF THE METHYL FORMATE PRODUCED. SODIUM FORMATE AND SULFURIC ACID ARE PREFERRED REACTANTS. METHANOL MAY BE RECOVERED BY INCREASING THE DISTILLATION TEMPERATURE TO AT LEAST THE BOILING POINT OF METHANOL.
