Esterquats, their intermediates, a process to make the esterquats, and their use as a fabric softener wherein said esterquats are of the formula: R4[R5R6N<+>Z]n X<->, wherein Z is covalently bonded to the nitrogen atom and selected from the group of formulae (I)-(IV), and isomers thereof, wherein R1 and R2 are independently selected from linear or branched, saturated or unsaturated C6-22 hydrocarbyl, R3 is nothing or C1-20 hydrocarbyl, R4 is C1-6 alkyl or independent Z, R5 is H, C1-6 alkyl, independent Z, or the residue of the quaternizing agent, such as C1-30 alkyl or alkenyl, preferably, C1-7 alkyl or alkenyl, R6 is C1-6 alkyl or independent Z, and X<-> is an ion selected from Cl<->, Br<->, l<->, F<->, CH3SO4<->, C2H5SO4<->, H2PO4<->, HPO4<2->, PO4<3->, H2PO3<->, HPO3<2->, H2PO2<->, HPO2<2->, nitrate<->, formate<->, acetate<->, propionate<->, tartrate<-> and benzoate<->, wherein the total charge of the anions equals the total charge of the cations and said process concerns the reaction of an unsaturated epoxide with an amine or a protonated amine, esterification of the formed intermediate, and optional quaternization. |
