Improvement of Thermal Oxidative Characteristics of Diesel Fuels With Esters of Cyclic Polyatomic Alcohols

Abstract

A number of symmetric, asymmetric and complex esters of 2,2,5,5-tetramethylolcyclopentanol and 2,2,6,6-tetramethylolcyclohexanol were synthesized, their physicochemical, viscosity-temperature and thermo-oxidative properties were studied. With the addition of these esters to hydrotreated diesel fuels 0.004% it was possible to significantly improve the operational properties of fuels: to increase thermal oxidative stability, flash point and lower pour point. Proceeding from these results, the esters of cyclic polyatomic alcohols are recommended as complex additives to diesel fuels
