    Abstract: The present invention is directed to a new industrial product, characterized in that it is essentially constituted by alpha esters of (A) hexahydrobenzoic acid, and of other aliphatic or cycloaliphatic carboxylic acids, containing from 6 to 20 carbon atoms, and wherein the average amount in moles of the acid or acids different from hexahydrobenzoic acid which are present, with respect to 1 mole of said polyvalent alcohol, is comprised between 0 and 2, with(B) at least one polyvalent alcohol having the general formula (1) R-CH2OH (1) wherein R represents a radical chosen among (a) -C (Y)2-CH2-O-CH2C(Y)3; (b) -CH2-(O-CH2-CH2) -OH and/or(c) -¢cH(CH3)-OCH2!nCH(CH3)-OH optionally mixed with a different polyvalent alcohol having the general formula (2) R1-CH2-OH (2) wherein R1 represents a radical chosen among(d) -C(Y)2CH2CH3; (e) -CY(CH3)2; (f) -CH(CH3)OH; (g) -C(Y)3, wherein Y in formulae (1) and (2) represents a group-CH2OH and n is a whole number from 1 to 20.

    Abstract: Prod. (I) comprises esters of (a) hexahydrobenzoic acid (HBA) and opt. other 6-20C (cyclo)aliphatic carboxylic acids with (b) at least one polyol (II) of formula RCH2OH (where R is a straight- or branched-chain aliphatic gp. contg. at least one OH gp. and opt. one or more ether O atoms). The av. no. of moles of acid(s) other than HBA per mole of (II) is 0-2. (I) are useful as base oils (or components thereof) for formulating lubricants, hydraulic fluids, oil emulsions, heat-transfer fluids etc. (esp. EP lubricants). They have good viscosity and stability properties.
