Basic compounds are prepared by heating hydroxylated aliphatic polyamines obtained by condensing hydroxyalkylamines with : a -g glycerindichlorhydrin or epichlorhydrin, with a fatty acid containing at least eight carbon atoms or an ester thereof at a temperature of 150-250 DEG C., and converting the resulting products into soluble salts. The latter are stated to have wetting, foaming, cleansing and softening properties and may be used for increasing the fastness of substantive dyeings since they form insoluble addition products (lakes) with substantive dyestuffs. In examples: (1) monoethanol-amine is condensed with a -g -glycerindichlorhydrin and the product heated with coconut fat, olive oil, castor oil, hardened fat, beef tallow and a naphthenic acid mixture: the basic products are converted into salts with acetic or lactic acid; (2) diethanolamine is condensed with a : g : glycerindichlorhydrin and the product heated with coconut fat, hardened fat, spermacetti, and stearic acid and then converted into salts: (3) hardened fat is heated with a hydroxylated polyamine obtained by condensing monoethanolamine with a : g -glycerindichlorhydrin at 130 DEG C. and again condensing with a : g -glycerindichlorhydrin at 125 DEG C. after adding caustic soda and driving off water. The use of wool fat is mentioned. The Specification as open to inspection under Sect. 91 comprises also the use of triethanolamine and propanolamines in the preparation of the hydroxylated aliphatic polyamines and states that the use of higher temperatures produces quaternary-polyamines such as [ClN(C2H4OH)3CH]2CHOH. This subject-matter does not appear in the Specification as accepted.
