Correlations between the structure, physical and rheological properties in the class of neopentylpolyol esters used as lubricating oils

Abstract

This paper examines the correlation between the physical and rheological properties of neopentypolyol ester used as a base oil for synthetic lubricants and the alkyl clash of the carboxylic acid used in preparation of the esters. Kinematic viscosity, viscosity index, flash point and freezing point were examined for fluids prepared by the authors, and their relationships to length and nature of the chains. The resulting data are presented.
