Abstract: THE INVENTION RELATES TO A PROCESS FOR OBTAINING ANHYDROUS OR SUBSTANTIALLY ANHYDROUS FORMIC ACID, IN WHICH FIRSTLY AQUEOUS FORMIC ACID IS PREPARED BY HYDROLYSIS OF METHYL FORMATE AND IS FREED FROM WATER IN THE SUBSEQUENT WORK-UP. THE PROCESS HAS THE SPECIAL FEATURE THAT STEAM, WHICH IS EMPLOYED FOR THE HYDROLYSIS OF METHYL FORMATE AND FOR HEATING A DISTILLATION COLUMN SERVING FOR WORK-UP, IS ALSO USED AS STRIPPING STEAM FOR WASTE-WATER STRIPPING. THE STRIPPED WASTE WATER IS PRODUCED DURING WORK-UP.
