Abstract
Synthetic lubricants comprise esters of the formula R-COOR1 in which R is an alkyl group having from 3 to 12 carbon atoms and R1 is an alkyl group having from 4 to 13 carbon atoms, the sum of carbon atoms in R and R1 being from 14 to 20 and one of the groups R and R1 being a straight chain and the other a branched chain. In an example caprylic acid, a branched C8 Oxo alcohol, toluene and sodium bisulphate, as catalyst, are heated to give the caprylic acid ester. Other esters were made by reacting a branched chain C8 Oxo alcohol with pelargonic and capric acids in a similar manner.ALSO:Synthetic lubricants comprise an ester of the formula RCOOR1 in which R is an alkyl group having from 3 to 12 carbon atoms and R1 is an alkyl group having from 4 to 13 carbon atoms, the sum of the carbon atoms in R and R1 being from 14 to 20, and in which one alkyl group is straight-chain and the other branched-chain. Examples of these esters given are the esters formed from a branched-chain C8 Oxo alcohol and caprylic, pelargonic and capric acids. These esters may be used directly as lubricants or may be blended with other lubricants such as mineral oils or other synthetic lubricants. Improvers such as viscosity index improvers, pour point depressors, oxidation inhibitors, detergents, corrosion resisting agents and rust inhibitors may be added.
