Abstract

Products stated to have wetting, foaming, dispersing, and cleansing properties are obtained by treating with a halide or anhydride of sulphuric acid or with amidosulphonic acid, a compound having the formula R.X.Y wherein R is an aromatic or hydroaromatic residue containing as a substituent at least one hydrocarbon residue with at least 3 carbon atoms, X is an alkyl residue united directly or by means of oxygen, nitrogen or sulphur with R, in the chain of which alkyl residue there may be one or more oxygen atoms and Y is NH2 or NHR<1> in end position in X, R<1> being an aliphatic hydrocarbon radicle. The products may be used in association with other washing agents, e.g. phosphoric acid salts or bleaching agents or with common salt or sodium sulphate. In an example, cyclohexylphenoxyethyl amine, which is prepared by treating cyclohexyl phenylglycol with thionylchloride and reacting the product with alcoholic ammonia, is converted into the sulphamic acid by means of chlorsulphonic acid in chloroform. The use of dibutylphenylethylamine, isohexyl phenylethylamine, and products obtained by reacting alkylated aromatic hydroxy or amino compounds with ethyleneimine or its homologues is mentioned. Samples have been furnished under Sect. 2(5) of products obtained by treating p-butylcyclohexylbutylamine with sulphurtrioxide, dodecylaminoethylaniline with amidosulphonic acid and a base obtained from methylamine and p-tert: octylphenyltriglycolether chloride with chlorsulphonic acid. Dodecylaminoethylaniline is obtained by condensing aniline with dodecylalcohol in the presence of zinc chloride and treating the dodecylaniline with ethyleneimine.ALSO:Products stated to have dispersing properties are obtained by treating with a halide or anhydride of sulphuric acid or with amidosulphonic acid, a compound having the formula R.X.Y, wherein R is an aromatic or hydroaromatic residue containing as a nuclear substituent at least one hydrocarbon residue with at least 3 carbon atoms, X is an alkyl residue united directly or by means of oxygen, nitrogen or sulphur with R, in the chain of which alkyl residue there may be one or more oxygen atoms and Y is NH2 or NHR<1> in end position in X, R<1> being an aliphatic hydrocarbon radicle. The products may be used in association with washing agents, e.g. phosphoric acid salts, or bleaching agents or with common salt or sodium sulphate. In an example, cyclohexylphenoxyethylamine is converted into the sulphamic acid by means of chlorsulphonic acid. The use of dibutylphenylethylamine, isohexyl phenylethylamine and products obtained by reacting alkylatedaromatic hydroxy or amino compounds with ethylenediamine or its homologues is mentioned.
