Abstract
Diamides having the general formula RCONH(XNH)n.XNH.COR1, wherein R is an alkyl radical having from 1 to 5 carbon atoms, R1 is an alkyl radical having from 9 to 20 carbon atoms, X is an ethylene radical and n is a small whole number, are prepared by reacting a polyethylene polyamine with a molecular proportion of a fatty acid acylating agent at a temperature between 110 DEG and 220 DEG C. so as to introduce an acyl group having not more than 6 carbon atoms and then reacting the product with another fatty acid acylating agent at 110 DEG to 220 DEG C., in molecular proportions so as to introduce an acyl group having from 10 to 21 carbon atoms, each step involving the removal of one molecular proportion of water or its equivalent per molecular proportion of amine or acylated amine used. In a modification, the higher fatty acid acylating agent may be reacted first. The acylating agents employed are the fatty acids themselves and the corresponding acyl halides and anhydrides and the acid esters. The compounds form salts readily with acids, e.g. acetic, formic, hydrochloric. The compounds and their salts are used as wetting, emulsifying and dispersing agents, detergents, dyeing assistants, textile lubricants and for breaking of petroleum emulsions of the oil-in-water type, and similar purposes. They are very useful as promoters for flotation of acidic minerals, e.g. feldspar, quartz, pyroxenes, the spineles, biotite, muscovite, clays, etc.; and particularly for the flotation of silica from phosphates. In examples, a mixture of polyethylene polyamines obtained by reacting ethylene dichloride with ammonia is condensed with acetic acid and cottonseed oil, palm oil, coconut oil, or oleic acid; the acetates of these diamides are described. Other reactants mentioned are: butyric, propionic and valeric acids, and as the higher acylating agents capric, lauric, myristic, palmitic, margaric, stearic, din-octyl acetic, arachidic, ricinoleic, naphthenic, abietic and pimaric acids and the esters of such acids occurring in animal and vegetable fats and oils such as palm kernel oil, linseed oil, olive oil, peanut oil, soya bean oil, castor oil, perilla oil, corn oil, sardine oil, shark oil, whale oil, seal oil, tall oil, and tallow; the esters of monohydric and polyhydric alcohols such as, for example, methyl stearate and glycol stearate, may also be used. The Specification as open to inspection under Sect. 91 includes the preparation of diamides having the above general formula in which R1 may also be a cycloalkyl radical and X may be an alkylene radical having 2 to 8 carbon atoms. Thus, in addition to polyethylene polyamines, there may be used propylene polyamines obtained by reacting propylene dichloride with ammonia, dibutylene triamine, tributylene tetramine, and diamylene triamine; and the higher acylating agents specified include hydrobenzoic and tetrahydrotoluic acids. This subject-matter does not appear in the Specification as accepted.
