Method for the distillative separation of a mixture containing vinyl ether and alchol

The calculation of the above balance shows that the division of stream () into the streams () and () used here leads to the fact that in the neutralization stage no excess sodium formate is produced, so that any ejection can be omitted. Furthermore, the water content of the stream () comprising sodium formate recirculated to the first crystallization stage in this case can be set to a very low value.

The present invention relates to a process for preparing formic acid by thermally decomposing ammonium formates of tertiary amines A, wherein the tertiary amine A on which the ammonium formate is based has a boiling point at atmospheric pressure in the range from 105 to 175&#xb0; C.

Method for the production of formic acid

The invention relates to a method for producing formic acid formates, whereby (a) formic acid methyl ester is partially hydrolysed with water; (b) formic acid methyl ester and methanol are separated by distillation from the reaction mixture obtained in step (a), forming a current containing formic acid and water; (c) the current obtained in step (b), containing the formic acid methyl ester and optionally methanol, is converted into a current containing formate and water, by (i) reaction with a basic compound having a pKvalue of the corresponding acid of the corresponding dissociation step of =3, measured at 25&#xb0; C. in an aqueous solution, in presence of water, and (ii) separation by distillation of the methanol; and (d) the current obtained in step (b), containing formic acid and water, and the current obtained in step (c), containing formate and water, are combined to form a mixture containing the formic acid formate and water. The invention also relates to a device for producing said formic acid formates and to the use of the same.
