1. A process for preparing an esteramide compound of following formula (I):
R1OOC-A-CONR2R3 (I) comprising a reaction step between: a diester compound of following formula (II):
R1OOC-A-COOR1 (II)and an amine of following formula (III):
HNR2R3 (III) in the presence of a basic compound, formulae in which:
A is a covalent bond or a straight-chain or branched divalent alkylene group comprising a number of carbon atoms ranging from 1 to 12,R1 is an optionally substituted hydrocarbon group, comprising from 1 to 36 carbon atoms,R2 and R3, the same or different, are groups chosen from the hydrogen atom and the hydrocarbon groups, optionally substituted, comprising from 1 to 36 carbon atoms,R2 and R3 are able together to form a ring comprising the nitrogen atom with which they are linked, the said ring optionally being substituted and/or comprising an additional heteroatom, andR2 and R3 not simultaneously being hydrogen atoms, wherein:
the amine of formula (III) in gaseous form and the basic compound are co-added to the diester compound of formula (II),and the reaction is conducted at a temperature of 30° C. or higher; wherein the diester compound of formula (II) is a mixture of diester compounds of following formulae (II.1), (II.2) and (II.3):
R1OOC—CH(CH3)—CH2—CH2—COOR1 (II.1)R1OOC—CH(CH2—CH3)—CH2—COOR1 (II.2)R1OOC—CH2—CH2—CH2—CH2—COOR1 (II.3). |
