Bench‐scale evaluation of nonvolatilealpha‐branched chain fatty esters as potential lubricants

Several nonvolatile esters of α‐branched fatty acids have been prepared in a highly purified state and examined by bench‐scale tests of the sort usually used in the preliminary evaluation of lubricants. Viscosity characteristics and Shell‐Boerlage wear‐test results for these compounds are comparable with those of compounds used in the manufacture of modern synthetic lubricants. These esters are substantially superior to one such compound in thermal stability and resistance to acid hydrolysis.
