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of from 50 to 150° C. in the presence of a metal alkoxide as catalyst in a reactor, in which a gas stream is withdrawn from the reactor, entrained methyl formate is removed from this gas stream by condensation, and all or some of the remaining gas stream is returned to the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: Formic acid-formates are produced by (a) partial hydrolysis of methyl formate (MF) with water, (b) distillation to give (S1) formic acid and water, (c) conversion of the other product from (b) (mainly MF) into a stream (S2) containing formate and water by reaction with aqueous strong base and distillation of methanol, and (d) combination of (S1) with (S2). A method for the production of formic acid-formates (I) involves: (a) partial hydrolysis of methyl formate (MF) with water; (b) distillation to give a stream (S1) containing formic acid and water; (c) conversion of the MF- and possibly methanol-containing stream from (b) into a formate- and water-containing stream (S2) by (i) reaction with a basic compound of an acid with a pKa value of at least 3 in presence of water followed by (ii) removal of methanol by distillation; and (d) combination of streams (S1) and (S2). An Independent claim is also included for apparatus for the production of (I), comprising: (A) a reactor for the hydrolysis of MF; (B) a distillation column for separating a stream containing MF, formic acid, methanol and water; (C) a column for the hydrolysis of MF with a basic compound with removal of methanol by distillation (with an inlet for the base above the inlet for the product from (B)); and (D) a column connected to the bottom of (B) for removing water from the stream containing formic acid and water.

Abstract: Acrolein or acrylic acid is prepared by catalyzing partial gas phase oxidation of propene, where a starting reaction gas mixture having propylene and molecular oxygen reactants and inert molecular nitrogen and propane diluent gasses is conducted at elevated temperature through a fixed catalyst bed whose active composition is a multimetal oxide having molybdenum, iron and bismuth. Preparation of acrolein or acrylic acid involves catalyzing partial gas phase oxidation of propene, where a starting reaction gas mixture having propylene and molecular oxygen reactants and the inert molecular nitrogen and propane diluent gasses and having the molecular oxygen and the propylene in a molar oxygen;C 3H 6 ratio of >=1 is conducted at elevated temperature through a fixed catalyst bed whose active composition is a multimetal oxide having molybdenum, iron and bismuth based on its total volume of 6-9 vol.% propylene, 8-18 vol.% molecular oxygen. 6-30 vol.% propane and 32-72 vol.% molecular nitrogen. The molar ratio V 1 of propane in starting reaction gas mixture to propylene in starting reaction gas mixture is 1-4. The molar V 2 of molecular nitrogen present in starting reaction gas mixture to molecular oxygen in starting reaction the mixture is 2-6, and the molar ratio of the molecular oxygen in starting reaction gas mixture to propylene in starting reaction mixture is 1.3-2.4.

Abstract: A process is proposed for preparing acid formates by providing a liquid stream I containing formic acid and a liquid stream II containing a metal formate, and mixing the liquid stream I with the liquid stream II, obtaining the corresponding acid formate, which comprises feeding, to the liquid stream I or a precursor thereof, to the liquid stream II or a precursor thereof, or to the mixture of the liquid streams I and II, a liquid stream III containing the following components at contents of in each case >0.1% by weight: metal formate, metal methoxide, methanol and MeFo (MeFo), which is produced in a process for preparing MeFo by carbonylating methanol in a reactor at a pressure up to 50 MPa absolute in the presence of a metal methoxide as homogeneous catalyst.
