Diesters of adamantanecarboxylic acids as promising components of base stocks for industrial synthetic oils

Аннотация

Viscosity–temperature properties and thermo-oxidative stability of polyoxyalkylene polyol and hydrogenated polyalphaolefin base stocks before and after introducing diesters of sebacic or 5,7-dimethyl-3-carboxy-1-adamantylacetic acids have been studied using high-pressure differential scanning calorimetry (PDSC) according to ASTM E2009. The potential for the use of diesters of the adamantane series as a component of a base stock for industrial synthetic oils instead of sebacic acid diester has been demonstrated.
