The invention relates to an improved process for the production of methyl formate, wherein a current of a gas containing carbon monoxide is reacted at elevated temperature (70.degree.-110.degree. C.) and pressure (20-110 bars) in a reaction zone with a recycled current of liquid reaction mixture containing

Process for the production of methyl formate

Process for the catalytic hydrogenolysis of maleic anhydride to give 1,4-butanediol and tetrahydrofuran in a single-stage operation by means of hydrogen under heat and pressure, in the presence of a suspension of a reduced solid catalyst, which contains as catalytically active elements Ni in association with Mo and/or W and optionally with Zr and/or Nb, having the following essential characteristics: (I) double oxidizing treatment of the solid catalyst in two stages before its reduction, and (II) conducting the hydrogenolysis of maleic anhydride at a temperature of from 170.degree. to 215.degree. C. under a hydrogen pressure below about 200 bars, in a reaction medium which contains gamma-butyrolactone, for a time such that the amount of gamma-butyrolactone in the final reaction medium is substantially equal to that present in the initial reaction medium.

Process for the production of 1,4-butanediol and tetrahydrofuran

The invention relates to an improved process for the production of a formamide, wherein a current of a gas containing carbon monoxide is reacted at elevated temperature (50.degree.-200.degree. C) and pressure (5-110 bars) in a reaction zone with a recycled current of liquid reaction mixture containing
