Abstract: Glycerol and aliphatic nitriles are simultaneously produced by treating liquid glycerides with gaseous ammonia at a rate of at least 200 liters of ammonia per kilogram of glyceride per hour at temperatures of from 220 DEG to 300 DEG C. in the presence of metal salts of carboxylic or sulfonic acids as catalysts and subjecting the product mixture to a phase separation into a nitrile phase and a glycerol/water phase. Preferred starting materials are vegetable and animal fats and oils.

Abstract: In the novel process for the purification of an alkylene oxide adduct which has been prepared using halogen-containing metal catalysts and contains halogen-containing compounds and metals as impurities, the alkylene oxide adduct to be purified is treated with an excess of the alkali metal compound, and the alkaline mixture obtained is brought to a pH of not more than 7 using an acid, with the proviso that the amount of water present in the resulting product mixture is at least 0.1% by weight, relative to the weight of the product. This product mixture is freed from water and other solvents, as a result of which the salts insoluble in the alkylene oxide adduct precipitate in the form of coarse crystals and can be easily separated off to give the desired pure alkylene oxide adduct.

Abstract: HOE 89/F 906 Process for the purification of alkylene oxide adducts A novel process for the purification of an alkylene oxide adduct which has bean prepared using halogen-containing metal catalysts and contains halogen-containing compounds and also metals as impurities comprises treating the alkylene oxide adduct which is to be purified with an excess of alkali metal compound and adjusting the pH of the alkaline mixture obtained to a value of at most 7 using an acid, with the proviso that the water content of the product mixture which is then present is at least 0.1 % by weight, relative to the weight of the product. This product mixture is freed from water and other solvents, this resulting in the precipitation in coarse crystalline form of salts which are insoluble in the alkylene oxide adduct and which can be easily separated off to isolate the desired pure alkylene oxide adduct.

Abstract: A process for the preparation of fatty acid esters of short-chain primary and secondary alcohols with 1 to 5 carbon atoms by transesterification of glycerides with the said short-chain alcohols is described. In this process, a stream of the gaseous alcohol is passed through the liquid glyceride at temperatures of at least 210 DEG C. and the product mixture of gylcerol and fatty acid alkyl ester is discharged from the reaction zone with this stream and is then subjected to phase separation.

Abstract: The new compounds consist essentially of ethylene oxide/propylene oxide block polymer units and oxyalkyleneated alkylphenol/aldehyde resin units, which are linked by methylene groups. They are prepared by reacting a block polymer of ethylene oxide and propylene oxide and an oxyalkyleneated alkylphenol/aldehyde resin with formaldehyde. The new compounds constitute especially advantageous breaking agents for petroleum.

Abstract: Water-soluble surface-active esters of di- to hexa-hydric aliphatic alcohols which have been reacted with propylene oxide and/or ethylene oxide and thereafter with at least two moles of a carboxylic acid of up to 22 carbon atoms are useful for dyestuff preparations. These preparations have good flow properties even with high dyestuff concentrations and low contents of said esters and optionally other surfactants and can be used in dyeing and printing procedures, especially in printing pastes for printing transfer sheets.
