The acid used will ordinarily be a monocarboxylic acid having from about 6 to 20 carbonatoms per molecule and may be of either branched or straight chain configuration.
Especially preferred, and contemplated in the preferred embodiment of this invention are the highly branched chain acids that are derived from aldehydes or alcohols obtained by subjecting an olefin to the action of carbon monoxide and hydrogen in the Oxo process. This process, described in detail in U. S. Patent No. 2,367,066, issued to Roelen in 1943, involves the use of temperatures in the order of 150 C. to 350 C. and pressures of about 3000 pounds persquare inch, or higher.- A cobalt catalyst is used. When hydrogen is used in conjunction with the carbon monoxide an aldehyde results which may be converted to the acid by oxidation. Further hydrogenation of the aldehyde results in the alcohol which may be converted to the acid by caustic fusion, or other of the well known processes. If water is used instead of hydrogen, the acid results directly from the Oxo process. Preferred olefins are the polymers or copolymers .of C, and/or C olefins, the resulting polymer and copolymers with other polymerizable materials, such as copolymers of fumarate or maleate esters with vinyl or copolymer having from about 7 to about 16 carbon I atoms.
By using as a starting material the reaction product of the alkylene oxide and the phosphoric acid, that is, the hydroxyphosphates and other materials suchas dibasic acids and alcohols, one may build complex molecules which have varying properties. prepared has the following schematic formula:
Aleohol-dibasic acid hydroxy-phosphate-dtbasle acid-alcohol ibasic acid aleohol The, new synthetic lubricants of invention may be thickened to grease compositions by using any of the com-,
mon grease forming soaps. The alkali or'alkaline earth metal soaps of high molecular weight substantially saturated fatty acids may be used and the grease compositions prepared by any of the methods withwhich the art is familiar. ,For instance, such soaps as the oleates, stearates, hydroxy stearates, or ricinoleates of sodium, potassium, lithium, calcium, barium, strontium, aluminum, and the like may be used, as well as the soaps formed by heating animal, fish, or vegetable oils, with soda, lime, baria hydrate or lithia hydrate.
If it is desired to enhance particular properties of the synthetic lubricants of invention, they may be blended with additive agents, such as viscosity index improvers, pour point depressants, detergent inhibitors, oxidation inhibitors, and the like. Such materials as ester polymers acetate, acrylate or methacrylate polymers or copolymers, phenyl alpha naphthylamine, phenothiazine, 2,6-di-tert.- butyl-para-cresol and many other additive materials may be blended with the synthetic lubricants of this invention.
The esters of invention may also find wide application in a great variety of industrial uses outside the lubricant field. For instance, these new esters may have utility as plasticizers, solubilizers, heat transfer agents, insecticides, weed killers, r-ust'preventatives,.solvents, dewaxing aids, detergents, oiliness agents as in penetrating oils, and as raw materials for many other industrial applications. They may be blended with mineral oils, with other synthetic lubricants such as formals, dibasic acid esters, complex esters, polymerized hydrocarbons, and the like.
To reiterate briefly, the instant invention relates to new and improved synthetic lubricants which comprise a material of the formula wherein R is an alkyl group containing from 5 to 19 carbon atoms, wherein R represents a divalent hydrocarbon radical containing from 2 to 4 carbon atoms, and
' wherein x, y, and z are integers of from 1 to 10. R may One complex ester so i be alike or ditferent and is preferably branched chain in configuration.
What is claimed is:
l. A process for preparing an ester of the formula wherein R is a monovalent hydrocarbon radical, R is a divalent hydrocarbon radical of fromZ to 4 carbon atoms and his an integer of from 1 to 10, which com- 3. A process according to claim 1 wherein said alkylene oxide is ethylene oxide and said acid is a C Oxo acid.
