    Abstract: A method for the production of formic acid-formates (I) involves (a) partial hydrolysis of methyl formate (MF) with water, (b) distillation to give formic acid and water (stream S1) and (c) combination of (S1) with the corresponding formate (F) to give a mixture of (I) and water. An Independent claim is also included for apparatus for the production of (I), comprising a reactor (A) for the hydrolysis of MF, a distillation column (B) for separating a stream containing MF, formic acid, methanol and water into MF, methanol and a stream (S1) containing formic acid and water, and a column (E) for removing water from S1.
