Abstract
Sulphonic acids of aliphatic amino ethers which are stated to be wetting, washing and emulsifying agents in the form of their salts with alkalies or organic bases, are prepared by acylating a sulphonic acid of an aliphatic amino-ether or a salt thereof with a fatty acid containing at least ten carbon atoms or a resin acid or a chloride thereof. The free sulphonic acids are stated to be carbonizing agents. Sulphonic acids of aliphatic amino ethers may be prepared by treating with ammonia or a primary amine the halogenated ether sulphonic acids obtained by reacting dihalogen aliphatic ethers with alkali or ammonium sulphite. In an example, b : b <1>-dichlordiethylether is treated with alcoholic sodium sulphite, and the resulting product treated with methylamine and acylated with lauric acid chloride. The latter may be replaced by abietic acid chloride, and ethylamine or aniline may be used instead of methylamine. The use of oleic, palmitic and linoleic acids is mentioned. The Specification as open to inspection under Sect. 91 comprises also the use of naphthenic, myristic, and oleostearic acids and the dihalogenated ethers obtained from an aldehyde, e.g. formaldehyde and hydrochloric acid, the condensation products of halogenated alcohols with aldehydes and hydrochloric acid and ethers of halogen hydrins of polyhydric alcohols. Dichlordimethylether, chlormethyl-b -chlorethylether, methylether of b : b :glycerine dichlorhydrin and alkylether of pentaerythrite di- or trichlorhydrin are specified starting materials. This subject-matter does not appear in the Specification as accepted.ALSO:Sulphonic acids of aliphatic aminoethers, which are stated to be emulsifying agents are prepared by acylating a sulphonic acid of an aliphatic amino ether or a salt thereof with a fatty acid containing at least ten carbon atoms or a resin acid or a chloride thereof.
