Abstract: In the process, a mixture of 99 to 5 mol % of at least one alkanol ethoxylate and 1 to 95 mol % of at least one carboxamide ethoxylate are reacted in the liquid state at 20 to 120 DEG C with 0.95 to 1 mol of chlorosulphonic acid or sulphur trioxide per 1 mol of -CH2CH2OH groups contained in the ethoxylates, and the reaction product is subsequently neutralised with an aqueous solution or suspension of an alkali metal, alkaline earth metal or ammonium hydroxide. This results in surfactant mixtures which are dissolved in water, contain ether sulphate and have a low content of 1,4-dioxane and which can be employed either directly or after low-cost removal of the small amounts of residual 1,4-dioxane as body care agents, dishwashing agents or detergents.

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: 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.
