Patent GB-372005-A (GB)
Title: Manufacture of ester-like wetting agents, foaming agents and dispersing agents
Filed: 1931-02-25
Abstract: Ester-like products having dispersing properties are prepared by condensing hydroxy derivatives of aliphatic or aromatic sulphonic acids, other than isethionic acid, but including aromatic and aliphatic aldehyde or ketone bisulphite compounds, or salts thereof, with saturated or unsaturated fatty acids containing at least six carbon atoms, or their derivatives.  The same products are obtained by condensing halogenated aliphatic, aryl-aliphatic or aromatic sulphonic acids, other than halogenated ethane sulphonic acids, or salts thereof with salts of said fatty acids.  In examples, the following pairs of components are condensed: sodium 1 : 2-hydroxybutanesulphonate and stearyl chloride, sodium chlormethanesulphonate and sodium oleate, formaldehyde bisulphite and oleic acid chloride, sodium 1 : 2-hydroxy-propane sulphonate and palmitic acid chloride. potassium 1 : 3-hydroxypropane sulphonate and oleic acid chloride, sodium ricinoleate and sodium benzylchloride sulphonate, oleic acid chloride and sodium p-phenolsulphonate, sodium 2 - naphthol - 6 - sulphonate, resorcinol-4 : 6-disulphonic acid, acetone bisulphite or the salt of the hydroxy sulphonic acid obtained by condensing sodium o -cresol with sodium a -chlor-b -hydroxypropane-a -sulphonate, the acid chloride of a bleached Montan wax fatty acid and sodium 1 : 2-hydroxybutanesulphonate, and naphthenic acid chloride and potassium 1 : 3-hydroxybutanesulphonate. The following components are also mentioned: brompropane-sulphonic acid, chlorbutanesulphonic acid, chlornaphthalenesulphonic acid, chlorphenolsulphonic acid.ALSO:Ester like products having soapy properties are prepared by condensing hydroxy derivatives of aliphatic or aromatic sulphonic acids, other than isethionic acid, but including aromatic and aliphatic aldehyde or ketone bisulphite compounds, or salts thereof, with saturated or unsaturated fatty acids containing at least six carbon atoms, or their derivatives. The same products are obtained by condensing halogenated aliphatic, aryl-aliphatic, or aromatic sulphonic acids, other than halogenated ethane sulphonic acids, or salts thereof with salts of said fatty acids. The products are stated to be wetting and emulsifying agents for use in the textile and leather industries.  In examples, the following pairs of components are condensed : sodium 1 : 2-hydroxybutanesulphonate and stearyl chloride, sodium chlormethanesulphonate and sodium oleate, formaldehyde bisulphite and oleic acid chloride, sodium 1 : 2-hydroxypropane sulphonate (prepared from propylene oxide) and palmitic acid chloride, potassium 1 : 3-hydroxypropane sulphonate (prepared from propylene oxide) and oleic acid chloride, sodium ricinoleate and sodium benzylchloride sulphonate (prepared by chlorinating sodium p-toluene sulphonate in dichlorbenzene), oleic acid chloride and sodium p-phenolsulphonate, sodium 2-naphthol-6-sulphonate, resorcinol-4 : 6-disulphonic acid, acetone bisulphite or the salt of the hydroxy sulphonic acid obtained by condensing sodium o-cresol with sodium a -chlor-b -hydroxypropane-g -sulphonate, the acid chloride of a bleached Montan wax fatty acid and sodium 1 : 2-hydroxybutanesulphonate, and naphthenic acid chloride and potassium 1 : 3-hydroxybutanesulphonate. The following components are also mentioned: brompropane sulphonic acid, chlorbutane sulphonic acid, chlornaphthalenesulphonic acid, chlorphenolsulphonic acid.  Specification 346,425 is referred to.
