Abstract: Catalysts (I), for the production of carboxylic acid salts from alcohols, comprise (wt.%): (1) copper; or (2) copper (10-99.9), iron (0.01-90) and at least one other metal (0-50). Catalysts (I) are optionally doped. The hydroxide is prepared by precipitation of copper salt solutions (and/or copper and iron salt solutions with salts of at least one other metal (A)) by coprecipitation with a base and reduction with hydrogen. An Independent claim is included for a process for the production of carboxylic acid salts by reaction of an alcohol of formula (II) with an alkali hydroxide and/or alkaline earth metal hydroxide in water. The reaction is in the presence of a catalyst (I), at 120-280 deg C, and at a pressure between the vapor pressure of water and 75 bar. R = -(OCH2CH2OH) or -NR R ; and R , R = H, phenyl, -CH2CH2OH, 1-20 C alkyl or 2-5C dialkylamino.

Abstract: The present invention relates to a process for the preparation of phosphonomethylglycine in which N-phosphonomethyliminodiacetic acid N-oxide is brought into contact with a catalytically active quantity of at least one catalyst, selected from amongst a thionyl halide, ammonium dithionite or an alkali metal dithionite, a dialkyl sulfite, sulfur dichloride, sulfur dioxide and sulfurous acid, in a reaction chamber by metering the N-phosphonomethyliminodiacetic acid N-oxide into the reaction chamber in such a way that always at least 50% of the N-oxide metered into the reaction chamber are converted.

Abstract: The production of diacetals (I) of glyoxal (II) from aqueous glyoxal and monohydric alcohols (III) with an acid catalyst (IV) involves leaving a mixture of (III) and (II) in contact with (IV) until the content of (I) is at least 70% of the equilibrium concentration. production of diacetals (I) of glyoxal (II) from 40-75 wt% aqueous glyoxal and monohydric alcohols (III) with acid catalyst (IV) involves leaving a mixture of (III) and (II) (mol ratio = at least 15:1) and not more than 8 wt% water in contact with (IV) until the content of (I) is at least 70% of the equilibrium concentration (without distilling off more than 5 wt% of the alcohol).

Abstract: A process is described fox preparing diacetals of glyoxal by reacting from 40 to 75% by weight aqueous glyoxal with monohydric alcohols in the presence of an acid catalyst, which comprises leaving a liquid mixture which, at the beginning of the reaction, comprises alcohol and glyoxal in a molar ratio of at least 15:1 and also water in a concentration of not more than 8% by weight in contact with the acid catalyst until concentration in the reaction mixture of the diacetal formed reaches at least 70% of the equilibrium concentration without more than 5% by weight of the alcohol used having already been distilled off.

Abstract: Described is a process for the preparation of phosphonomethylglycine in which N- phosphonomethyliminodiacetic acid N-oxide is brought into contact with a catalytically active quantity of at least one catalyst. The catalyst may be selected from a thionyl halide, ammonium dithionite or an alkali metal dithionite, a dialkyl sulfite, sulfur dichloride, sulfur dioxide and sulfurous acid. The reaction is carried out in a reaction chamber by metering the N-phosphonomethyliminodiacetic acid N-oxide into the reaction chamber in such a way that always at least 50% of the N-oxide metered into the reaction chamber is converted.
