    Abstract: A description is given of a process for preparing methyl formate by reacting excess methanol with carbon monoxide under superatmospheric pressure and at elevated temperature in the presence of alkali metal methoxide or alkaline earth metal methoxide as catalyst in a pressure-rated reactor, in which the use of at least two reactor elements, preferably operated in countercurrent, at about 100° C. and a pressure of about 100 bar in combination with a solids-free desalting of the reaction product makes possible very economical, largely trouble-free production of methyl formate in any desired quality and with a very good production capacity. Furthermore, the process for solids-free desalting and apparatuses for carrying out this process are described.

    Production of anhydrous formic acid involves hydrolysis of methyl formate followed by distillation, extraction with amide and further distillation stages, using the same extractant to wash useful products out of the off-gas

    Abstract: In the production of anhydrous formic acid (FA) by hydrolysis of methyl formate (MF) followed by distillation, extraction of the bottom product with an amide extractant (I) and further distillation stages, the off-gas streams containing MF and/or methanol and/or FA are washed with (I) which is then returned to the process along with these products in solution. The production of (essentially) anhydrous formic acid (FA) involves: (i) hydrolysis of methyl formate (MF), (ii) removal of methanol and excess MF by distillation, (iii) liquid-liquid extraction of the bottom product with an amide of formula R (R )NC(O)R (I), (iv) distillation of the extract, (v) recycling the top product from (iv) (containing water and some FA) to the lower part of the distillation column used in stage (ii), (vi) separation of the bottom product from (iv) by distillation into anhydrous FA and extractant (I) and (vii) recycling (I) into the process. In this process, the off-gas streams containing MF and/or methanol and/or FA are washed with extractant (I), which is then returned to the process along with dissolved MF and/or methanol and/or FA. R , R = alkyl, cycloalkyl, aryl or aralkyl, or R plus R plus the linking nitrogen may form a 5- or 6-membered heterocycle, with the proviso that only one of these groups is aryl; R = H or 1-4C alkyl An Independent claim is also included for the apparatus used for this process, comprising a synthesis reactor (6), a hydrolysis reactor (1), a distillation system (2) for stage (ii), a distillation system (4) for stage (iv), an extraction unit (3), a distillation system (5) for stage (vi) and an off-gas scrubber (9).
