Abstract: A textile softening detergent composition contains from 5 to 70 wgt % surfactant, from 0.5 to 50 wgt % builder, from 1 to 20 wgt % crystalline laminated silicic acid and/or a corresponding alkali metal silicate and standard detergent aids. It is characterized in that the crystalline laminated silicic acid or its alkali metal salt of the general formula M2SixO2x+1xy H2O in which x stands for a number larger than 7.0, M stands for sodium, potassium or hydrogen, and y stands for a number of from 0 to 25, shows one or more reflexes unassignable to quartz, tridymite and cristobalite in the X-ray diffraction diagram in the range of the d-values of 3.0-4.0x10-8 cm. Process for rinsing textiles using the crystalline laminated silic acid or its alkali metal salts as a textile softening agent.

Abstract: The invention relates to a process wherein an alcohol and/or phenol is reacted with phosphorus pentasulfide in the presence of a catalyst which is selected from (a) phosphonium salts of the general formula: I (b) ammonium salts of the general formula: II (c) phosphine oxides of the general formula: III (d) phosphine sulfides of the general formula: IV (e) phosphinic acid derivatives of the general formula: V In formulae I through V, the substituents R1, R2, R3 and R4 each stand for identical or different alkyl-, aryl-, alkaryl- or aralkyl- groups having from 1 to 22 carbon atoms. A stands for an inorganic or organic acid, and X and Y, respectively, stand for both oxygen and sulfur, and M stands for a monovalent metal or oxygen.

Abstract: The invention relates to an improved process for making amine salts of acid O,S-dialkylthiophosphoric acid esters of the general formula (I) (I) in which R1 stands for the ammonium ion of primary or secondary aliphatic, cycloaliphatic or aromatic amines or of a heterocyclic nitrogen base and R2 and R3 each stand for an alkyl group by subjecting an O,O,Strialkyl-thiophosphate to partial dealkylation and forming the salt of the dealkylated product by treatment with an amine corresponding to the ammonium ion R1. In the improved process an O,O,S-trialkylthiophosphate of the general formula (II) (II) in which R2 and R3 have the meanings given above, is mixed with at least stoechiometric proportions of water and an amine corresponding to the ammonium ion R1, the resulting mixture is reacted, with agitation, over a period of about 3 to 8 hours at a temperature within the range 0 to 120.degree. C, and the amine salt of the general formula (I) is separated from the reaction mixture.
