Conclusions
-
1.
Esters of the cyclic butyral of trimethylolpropane and mixtures of C7-C9 or C10-C16 acids were synthesized.
-
2.
According to their physicochemical properties, the esters obtained can be used as components of synthetic oils.
-
3.
A thickened lubricating oil was obtained, consisting of esters synthesized on the basis of the cyclic butyral of trimethylolpropane, as viscous additive — the copolymer of methacrylate and vinylpyridine — and an oxidation inhibitor — p-hydroxydiphenylamine.
