    Abstract: The claimed polyhydroxy amide sulphosuccinates have formula (1), where R is an alkyl group, R CO is an acyl group, y is a number between 3 and 9 and Z(OX)y is a polyhydroxy hydrocarbon group partially esterified with maleic acid or maleic acid anhydride and subsequently sulphited, and X is hydrogen or a sulphosuccinate group. The claimed sulphosuccinates and in particular mixtures thereof with fatty alcohol alkoxylate-sulphosuccinates have among other things very good foaming qualities, very good skin compatability and an unexpectedly high capacity for thickening in combination with standard ether sulphates and alkali metal salts such as sodium chloride.

    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: 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.

    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: of the disclosure: The new petroleum breakers are obtained by sub jecting a) an addition reaction product which has been obtained by reacting aliphatic aldehydes with phenol in a molar ratio of 1:1 to 3:1 at temperatures of 50 to 80.degree.C in the presence of an alkaline catalyst, to a condensation reaction at 80 to 150.degree.C, after prior neutralization and, if appropriate, in the presence of inert solvents, with-b) a block polymer which has been prepared by reacting polypropylene glycols having molecular weights of 1,300 to 3,000 with 20 to 100% by weight of ethylene oxide in the presence of alkaline catalysts, in a ratio of 0.5 to 4 moles of a) to 1 moLe of b), and removing the water of the reaction which is formed, and c) adding on 10 to 400 g of propylene oxide, relative to 100 g of condensation product, or 10 to 200 g of ethyLene oxide and propylene oxide in a ratio of 1:0.5 to 14, relative to 100 g of condensation product, in an addition reaction, to the etherfied phenol/aldehyde condensation product thus obtained. When used for separating petroleum emulsions, they effect, in particular, a high and rapid removal of salt.

    Abstract: The new petroleum breakers are obtained by reacting, at 90 DEG to 160 DEG C. and at a pH value of 6 to 9, (a) an addition product which has been obtained by reacting phenol with formaldehyde or acetaldehyde in a molar ratio of 1:1 to 3 at a temperature of 50 DEG to 80 DEG C., in the presence of an alkaline catalyst, with (b) a block polymer which contains nitrogen and which has been obtained by an addition reaction in which 10 to 80 moles of ethylene oxide and propylene oxide are added on, as a statistical average per nitrogen atom, the molar ratio of ethylene oxide to propylene oxide being 1:0.5 to 14, to ethylenediamine, propylenediamine, polyethylenepolyamines, polypropyleneamines or mixtures thereof, the ratio being 1 to 20 moles of (a) to 1 mole of (b). They are distinguished by a high degree of effectiveness when used for separating petroleum emulsions. Products which in some cases have an even greater effect are obtained if the reaction product of (a) and (b) is propoxylated.
