Title
(EN) COMPOSITIONS OF ESTERS OF FLUOROSUBSTITUTED ALCANOIC ACIDS
(FR) COMPOSITIONS D'ESTERS D'ACIDES ALCANOÏDES FLUOROSUBSTITUÉS
Abstract
(EN)
Composition of esters of fluorosubstituted alcanoic acids, comprising or consisting essentially of a compound of a formula selected from the group consisting of: RCFCIC(OAc)=CHC(O)OR1 (II); RCFHC(O)CH2C(O)OR1 (IV); RCFHC(OAc)=CHC(O)OR1 (V); and RCFHCH(OAc)CH2C(O)OR1 (VI); or of compounds of formula (I) RCFCIC(O)CH2C(O)OR1 and of formula (II); of compounds of formulae (IV) and (V); or of compounds of formulae (IV) and (VI); wherein R is C2F5, CF3 or F and R1 is an alkyl group with from 1 to 4 carbon atoms, an alkyl group with from 1 to 4 carbon atoms substituted by 1 or more fluorine atoms. A process for the reduction of the compound of formula (I) and/or formula (II), and compositions resulting from such reduction. A process for the separation of the compound of formula (I) from the compound of formula (II) comprising subjecting a composition comprising such compounds to a distillation operation.
