Abstract

The invention relates to a mixture of diesters of adipic acid suitable for use as synthetic lubricating oils, obtained by esterifying the acid with the mixture of C7 alcohols obtained from a C6 olefine, preferably propylene dimer, by the oxo synthesis. The alcohols may be prepared by carbonylation of the olefine at about 300 DEG to 400 DEG F. under pressures of about 1000 to 3000 p.s.i. in the presence of a heavy metal carbonyl, followed by hydrogenation of the resulting aldehydes. The esterification may be effected using toluene sulphonic acid as catalyst and toluene as a water-entrainer. An example is given wherein the esters are purified by treatment with Attapulgus clay and fractional distillation; the lubricating properties of the ester-mixture are compared with those of the adipates of various other alcohols and alcohol-mixtures. Specification 670,507 is referred to.
