Title: Improvements in or relating to oily rust inhibiting composition
IPC: C09D5/08

Abstract: A salt is formed by direct addition of an aliphatic or cycloaliphatic carboxylic acid containing 6-24 carbon atoms to a hydroxyaliphatic amine of formula <FORM:0681555/IV (b)/1> where any or each of R, R1 and R11 is a radical of the structure <FORM:0681555/IV (b)/2> where R111 is hydrogen or an aliphatic hydrocarbon radical containing 1-12 carbon atoms, with or without at least one hydroxyl group, any remaining radicals being hydrogen or aliphatic hydrocarbon radicals containing 1-8 carbon atoms, with or without at least one hydroxyl group.  The acids may contain straight or branched chains, may be saturated or unsaturated and may contain one, two or more carboxyl groups.  Acids specified are lauric, palmitic, stearic, oleic, linoleic, ricinoleic, eleomargaric, erucic, behenic, arachidic and lignoceric acids, naphthenic acids, acids derived from the oxidation of petroleum products or of aldehydes produced from olefins, carbon monoxide and hydrogen or water, and fatty acids derived from tall oil, castor, soybean, linseed, olive, tung, rapeseed and menhaden oils.  In an example dimethylol methyl amino methane is heated to 130 DEG  C. and then added to an equimolecular amount of oleic acid.  The mass is again heated and the amine salt is formed.  The preparation of monomethylol dimethyl amino methane oleate and trimethylol amino methane oleate is also mentioned.  Specification 681,554 is referred to.ALSO:A lubricating composition consists of an oily base containing 0.01-10 per cent by weight of a salt of an aliphatic or cycloaliphatic carboxylic acid containing 6-24 carbon atoms and a hydroxyaliphatic amine of the formula:-  <FORM:0681555/III/1> where from 1-3 of the radicals R, R1 and R11 are radicals of the type- <FORM:0681555/III/2> where each R111 is hydrogen or an aliphatic hydrocarbon radical containing 1-12 carbon atoms, with or without at least one hydroxyl group, any remaining radicals being hydrogen or aliphatic hydrocarbon radicals containing 1-8 carbon atoms, with or without at least one hydroxyl group.  Acids specified are lauric, palmitic, stearic, oleic, linoleic, ricinoleic, eleomargaric, erucic, behenic, arachidic and lignoceric acids, naphthenic acids, acids derived from the oxidation of petroleum products or of aldehydes produced from olefins, carbon monoxide and hydrogen or water and fatty acids derived from tall oil, castor, soybean, linseed, olive, tung, rapeseed and menhaden oils. Salts mentioned are the oleic acid salts of monomethylol - dimethyl - amino - methane, dimethylol-methyl-amino-methane and trimethylol-amino-methane.  Oil bases referred to are petroleum oils and synthetic oils such as those obtained by the polymerization of olefins, by the hydrogenation of coal, or by the esterification of polycarboxylic acids or of polyhydroxyalcohols.  Mixtures of naphtha and a lubricating oil, with or without small amounts of petrolatum or degras, may also be used. Optional ingredients of the composition mentioned are heat-thickened fatty oils, sulphurized oils, organo-metallic compounds, soaps, sludge-dispersers, anti-oxidants, thickeners, viscosity index improvers, oiliness agents, olefin polymers, resins, colloidal solids such as graphite or zinc oxide, and solvents and assisting agents such as esters, ketones, alcohols, aldehydes and halogenated and nitrated compounds.  Specification 681,554 is referred to.
