The X-ray structures and proton and carbon-13 NMR spectra have been ob
tained for two dicyclohexyl esters and one tricyclohexyl ester: namely
, di-2-methylcyclohexylsuccinate (D2MCS), dicyclohexyl-3,4-furandicarb
oxylate (DCFDC) and tricyclohexyl-1,2,3-propanetricarboxylate (TCPTC).
These esters are models for high-traction fluids. It was shown that t
he molecular modelling calculations we performed (on DCFDC and TCPTC)
are not adequate for determining the minimum energy configuration of t
he compounds investigated.
