    Abstract: The invention relates to a process for the preparation of methyl formate by reacting methanol with carbon monoxide at a pressure of from 0.5 to 10 MPa abs. and a temperature of from 50 to 150° C. in the presence of a metal alkoxide as catalyst in a reactor, in which a gas stream is withdrawn from the reactor, entrained methyl formate is removed from this gas stream by condensation, and all or some of the remaining gas stream is returned to the reactor as circulating-gas stream and a mean gas superficial velocity of from 1 to 20 cm/s is set in at least one region of the reactor in which the gas flows essentially in one direction.

    Abstract: A process is proposed for preparing acid formates in which a liquid stream I comprising formic acid and a liquid stream II comprising a metal formate are prepared, the liquid streams I and II are fed to a rectification column in such a manner that a higher or identical feed point to the rectification column is chosen for the liquid stream II than for the liquid stream I, the liquid streams I and II are mixed in the rectification column, with water being removed overhead from the rectification column and a bottoms stream comprising the acid formate is taken off from the rectification column, which comprises the bottoms stream being produced as melt comprising less than 0.5% by weight of water.

    Abstract: The aim of the invention is to identify and provide a substance that influences the protein concentration of animal organisms as well as to provide preparations based on said substance for use in food for animals and humans. Said aim is achieved by using tartronic acid or the derivatives thereof. The invention thus relates to the use of tartronic acid or the derivatives thereof for producing preparations that are suitable for increasing the protein concentration of animal organisms. Also disclosed is the use of preparations containing tartronic acid or the derivatives thereof in animal fodder or food for humans.

    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.
