Abstract

Synthetic lubricants comprise esters of the general formula <FORM:0716086/IV (b)/1> in which R and R1 are alkyl radicals having from 3 to 9 carbon atoms in a straight chain and n is a number from 1 to 6. The glycols from which the esters are derived may be prepared by reacting propylene glycol with propylene oxide. The mixture of polypropylene glycols obtained is fractionated to yield the glycols in which n varies from 1 to 6. The glycols are esterified by reacting them with acids containing from 4 to 10 carbon atoms per molecule. In an example dipropylene glycol is esterified with n-octanoic acid using toluene as a solvent in the presence of sodium bisulphate. Other esters referred to are tripropylene glycol di-n-octanoate and tripropylene glycol dicaproate.ALSO:Synthetic lubricants comprise an ester of the formula <FORM:0716086/III/1> in which R and R1 are alkyl radicals having from 3 to 9 carbon atoms in a straight chain and n is a number from 1 to 6 Examples of these esters are the di-n-octanoic acid ester of dipropylene glycol and the di-caproic and di-n-octanoic acid esters of tripropylene glycol. The esters may be blended with other lubricating oils such as mineral oils or other synthetic lubricants or with viscosity index improvers, pour point depressors, oxidation inhibitors, rust inhibitors or corrosion resisting agents.
