    Abstract: The invention relates to a method of producing methyl formiate by reacting excess methanol with carbon monoxide under increased pressure and increased temperature in the presence of an alkalimethylate or alkaline earth methylate as the catalyst in a pressure-proof reactor. The inventive method uses at least two reactor elements, preferably countercurrent reactors, at a temperature of approximately 100 DEG C and a pressure of approximately 100 bar in combination with a solid-matter free desalination of the reactor product. The inventive method provides a means for producing methyl formiate of any quality desired and with an excellent production capacity in a very economical and complication-free manner. The invention further relates to a method of solid-matter free desalination and to devices for carrying out the inventive method.

    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.
