Title: Improvements in the production of detergent solutions
Filed: 1931-05-11
Abstract: Emulsifying and detergent agents are obtained by sulphonating alkylbenzylethers in which the alkyl groups are saturated and contain not less than six carbon atoms.  The benzene ring of the benzyl residue may contain substituents such as methyl or chlorine.  The detergent action of the products is improved by the presence of soaps or inorganic salts having the same kations as the detergents themselves.  Dry solid compositions may be prepared by the addition of such inorganic salts to the soluble salts of the sulphonated alkylbenzylethers.  In examples: (1) sulphuric acid monohydrate is used to sulphonate dodecylbenzylether, cetylbenzylether and octadecylbenzylether: (2) sodium chloride is mixed with the sodium salt of cetylsulphobenzylether to form a detergent: (3) another detergent comprises sodium sulphate, the sodium salt of cetylsulphobenzylether and the sodium salt of dodecylsulphobenzylether.ALSO:Wetting, emulsifying and detergent agents which may be used for example for washing raw wool, are obtained by sulphonating alkylbenzethers in which the alkyl groups are saturated and contain not less than six carbon atoms.
