Abstract: 337,737. Johnson, J. Y., (1, G. Farbenin dustrie Akt.-Ges.). April 27, 1929. Sizes.-Products which are stated to be useful in the manufactune of sizes and finishes are prepared by condensing mono amines, containing only one hydroxyalkyl group and free from aromatic groups with aliphatic carboxylic, sulphonic or sulphonated carboxylic acids containing at least 8 carbon atoms in the molecule, or their esters or halides, the condensation being effected at a temperature substantially above 100‹C. when the free acids or their esters, are used, so as to convert the salts which are first formed into acid amides, esters or ester-amides. The products may be treated with alkylating agents e.g. alkyl halides, and oxyalkyl groups may be introduced by treating with alkyleneoxides. Since the products are usually basic in character they may be converted into salts by means of acids e.g. hydrochloric, hydrobromic, sulphuric, lactic, oleic, phthalic and sulphonic acids of aliphatic, aromatic, hydro-aromatic or heterocyclic compounds. When hydroxy groups or double bonds are present, the products may be esterified with inorganic or organic acids. One molecule of the hydroxy-alkylamine may be condensed with one or two molecules of the aliphatic acid; in the latter case different acids may be used and the condensation may be effected in stages. Suitable aliphatic acids specified are long chain fatty acids, aliphatic mono or polybasic hydroxycarboxylic acids, aliphatic poly-carboxylic acids, turkey-red oils and aliphatic sulphonic acids which may contain halogen, hydroxyl, amino or alkylamino groups as substituents. According to examples : (1) ethanolamine mono-n-propanol-amine or mono-iso-butanolamine is heated with stearic acid and the resulting ester converted into an oleic acid amide by further heating with oleic acid or its chloride. Instead of stearic acid, aliphatic sulphonic acids or sulphuric esters may be used, and the ester-amide produced may be converted into a salt with an inorganic or organic acid; (2) n-butanolamine is heated with hydroxystearicchloride, zinc chloride being used as condensing agent. Alkyl groups or hydroxyl alkyl groups may be introduced into the amino groups of the product : (3. Dimethyl ethanolamine is condensed with oleic acid : (4) 1 mol. of ethanolamine is condensed with 2 mols. of a-hydroxy-stearic acid a.nd the product esterified with sulphuric or phosphoric acid. The activity of the products may be increased by mixing therewith protective colloids, e.g. glue, gelatine, gums, vegetable mucilages, sulphite cellulose liquor, soap or saponaceous substances or organic solvents. The products may also be added to starch, glue, white of egg, casein, magnesium sulphate aluminium acetate or sulphate or other ingredients commonly employed in the manufacture of sizing and finishing agents for use in the textile industry. Specifications 295,024, 306,116 and 328,675, [all in Class 2 (iii), Dyes &c.]. are referred to. Reference has been directed by the Comptroller to Specifications 24631/03, [Class 2, Acids and salts, Organic &c.], and 290,790, [Class 2 (iii), Dyes &c.].
