Abstract:
A process for preparing an esterquat composition comprising(a) reacting a tertiary amine according to formula I: whereinR1 represents a C3-C6 hydrocarbon group, R2 represents a C3-C6 hydrocarbon group, a â€”R4â€”OH group or a â€”CH2[CH(OH)]nCH2OR5 group, if R2 represents a C3-C6 hydrocarbon group, R3 represents a â€”R4â€”OH group or a â€”CH2[CH(OH)]nCH2OR5 group, if R2 represents a â€”R4â€”OH group, R3 represents a â€”R4â€”OH group or a â€”CH2[CH(OH)]nCH2OR5 group, if R2 represents a â€”CH2[CH(OH)]nCH2OR5 group, R3 represents a â€”CH2[CH(OH)]nCH2OR5 group, R4 represents a C2-C4 hydrocarbon group, n is 1-4, and R5 represents H or a C1-C30 hydrocarbon group, with a C3-C6 hydrocarbyl halide or a di(C3-C6) hydrocarbyl sulfate, followed by (b) reaction with a C8-C30 acid halide, with the proviso that at least one hydroxy group is esterified.
