Abstract
Hydroxy aliphatic ether acids of the formula <FORM:0683962/IV (b)/1> where R1 and R2 are alkyl groups of 3-12 carbon atoms, R3 is an alkyl group of 2-6 carbon atoms and m is an integer preferably less than 4, are prepared by reacting appropriate hydroxy acids with an olefin oxide, such as ethylene or propylene oxide. A Friedel-Crafts catalyst, such as boron trifluoride or stannic tetrachloride may be used. In an example, hydroxy stearic acid is dissolved in toluene containing stannic tetrachloride and ethylene oxide bubbled into the mixture, at a temperature of 50-60 DEG C. The solvent is removed by heating the reaction mixture on a steam bath. Specified products are the hydroxyethyl ether of 12-hydroxy stearic acid, 8 - (b - hydroxy - ethoxy) - stearic acid, 12 - (b - hydroxy - a - propoxy) - ricinoleic acid and 10 - (b - hydroxy - isobutoxy) - palmitic acid. The acids may be converted to their soaps by reacting with a metal oxide, hydroxide or carbonate, especially those of the alkali metal soaps such as lithium, and of calcium, barium and aluminium.ALSO:A lubricating grease composition comprises a lubricating oil thickened with from 3-40 per cent by weight (based on the total composition) of a metal soap or mixture of metal soaps, at least one-third by weight of which is a soap of a branched-chain hydroxy aliphatic ether acid of 10-44 carbon atoms. The acid may have the formula <FORM:0683962/III/1> where R1 and R2 are alkyl groups of 3-12 carbon atoms, R3 is an alkyl group of 2-6 carbon atoms and m is an integer preferably less than 4. Specified acids are the hydroxyethyl ether of 12-hydroxy stearic acid, 8-(b -hydroxy-ethoxy)-stearic acid, 12-(b -hydroxy-a -propoxy)-ricinoleic acid and 10 - (b -hydroxy - isobutoxy) - palmitic acid. The alkali metal soaps, especially lithium soaps, or calcium, barius and aluminium soaps may be used. Conventional soaps, such as the stearic acid or hydrogenated fish oil acid soaps of lithium and calcium, and low molecular weight salts, such as acetates, acrylates, propionates and furoates, and other conventional additives, may also be added to the composition. The lubricating oil may be a mineral oil or a synthetic oil such as a synthetic ester, for example di-2 ethylhexyl sebacate or the tri-ethylene glycol ester of 2-ethylhexanoic acid. Examples are given of the preparation of the greases.
