Basic products are made by reacting the primary amide of a carboxylic acid derived from a naturally occurring oil, fat, or wax or a mixture of such amides with three or more molecular proportions of ethylene imine at elevated temperature, if desired in presence of a catalyst. The products may combine with acids to form salts. Catalysts specified are sodium hydroxide or a surface-active substance such as silica gel or kieselguhr. Three to forty molecular proportions of ethylene imine are preferred, but larger quantities may be used. Primary amides of the following acids are specified; caproic, caprylic, capric, lauric, myristic, palmitic, stearic, hydroxystearic, oleic, linoleic, linolenic, ricinoleic, elaidic, undecylenic and erucic, and mixtures of these acids derived from natural oils such as coconut oil, palm oil, palm-kernel oil, rapeseed oil, linseed oil, cotton seed oil, the acids obtainable by fat hydrogenation processes, and the acids of waxes of vegetable, animal, or mineral origin such as beeswax, carnauba wax, montan wax. Salts of the products may be formed by treatment with aqueous acids or by dissolving in an organic solvent, such as benzene, chloroform or ethanol, and treatment with acids, e.g. by passing in gaseous hydrogen chloride. The aqueous solutions of the salts are useful in textile treatment processes. In an example, stearic acid amide is heated to 130 DEG C. for 10 hours with ethylene imine in presence of aqueous sodium hydroxide; the product is dissolved in ethanol and treated with hydrogen chloride. Samples have been furnished under Sect. 2 (5) of products prepared by (A) reacting mixed amides derived from the fatty acids of coconut oil with five molecular proportions of ethylene imine in a closed vessel for 12 hours at 130 DEG C. in presence of a little water to give a basic intermediate product, which is then treated with hydrogen chloride in ethanol and acetone; (B) reacting the intermediate product under (A) with a further five molecular proportions of ethylene imine; (C) reacting the product obtained under B with a further five molecular proportions of ethylene imine; (D) dissolving the product of (C) in acetone and treating with hydrogen chloride; (E) reacting lauric acid amide with five proportions of ethylene imine and a little water in a closed vessel at 160 DEG C. for 14 hours, and then reacting the product with a further five proportions of ethylene imine. These products are stated to be foaming agents. |
