Abstract
Products having the formula RCOXR1SO3Z in which R is an aliphatic radical having more than one double bond and more than eight carbon atoms, X is O, NH, N-alkyl, N-aralkyl or N-aryl, R1 an aliphatic radical and Z an alkali metal, ammonium or hydrogen, are stated to be emulsifying agents. They readily emulsify oils and fats with or without the use of soap. In examples, the reaction product of the fatty acid chloride of train oil with hydroxyethane sulphonic acid or with aminoethanesulphonic acid is employed. The action of the fatty acid amides is increased by introducing a methyl, ethyl or benzyl group. The Specification as open to inspection under Sect. 91 comprises also the use of compounds having the formula RXR1SO3Z in which R1 and Z are as defined above, R is any aliphatic radical containing more than eight carbon atoms and X is O, S, OCOO, COO, NY, CONY, OCONY or YNCONY, Y being hydrogen, alkyl, aralkyl or aryl. In further examples, b - cresoxyl - a - oleyl - hydroxypropanesulphonic acid, the sodium salt of oleylmethylamino ethanesulphonic acid, oleylhydroxyethanesulphonic acid, oleylaminoethanesulphonic acid and the products obtained by condensing sodium b - cresoxyl - a - oleylhydroxypropanesulphonate with formaldehyde, and chlorcarbonicdodecyl ester with hydroxyethanesulphonic acid or with amino- or methylaminoethanesulphonic acid are employed. Palmitylhydroxyethanesulphonic acid is also mentioned. This subject-matter does not appear in the Specification as accepted.ALSO:Products having the formula RCOXR1SO3Z in which R is an aliphatic radical having more than one double bond and more than eight carbon atoms, X is O, NH, N-alkyl, N-aralkyl or N-aryl, R1 an aliphatic radical and Z an alkali metal, ammonium or hydrogen, are stated to be tanning, greasing and penetrating agents. They may be added to dyebaths for dyeing leather, e.g. in topping with basic dyestuffs. In examples, the reaction product of the fatty acid chloride of train oil with hydroxyethane sulphonic acid or with aminoethanesulphonic acid is employed. The action of the fatty acid amides is increased by introducing a methyl, ethyl or benzyl group. The Specification as open to inspection under Sect. 91 comprises also the treatment of hides with compounds having the formula RXR1SO3Z in which R1 and Z are as defined above and R is any aliphatic radical containing more than eight carbon atoms and X is O, S, OCOO, CCO, NY, CONY, OCONY or YNCONY, Y being hydrogen, alkyl, aralkyl or aryl. In further examples, b -cresoxyl-a -oleyl-hydroxypropanesulphonic acid, the sodium salt of oleylmethyl-aminoethanesulphonic acid, oleylhydroxyethanesulphonic acid, oleylaminoethanesulphonic acid and the products obtained by condensing sodium b -cresoxyl-a -oleylhydroxy-propanesulphonate with formaldehyde and chlorcarbonicdodecyl ester with hydroxyethanesulphonic acid or with amino- or methylaminoethanesulphonic acid are employed.
