    摘要: This invention provides a process for producing a quaternary ammonium salt having an ester group easily with small amounts of side products. Disclosed is a process for producing a quaternary ammonium salt having ester group(s), which comprises reacting a quaternary ammonium salt (1) having a hydroxy group(s) with a fatty acid anhydride (2) to esterify all or part of the hydroxyl groups of the quaternary ammonium salt (1).

    wherein X - represents an anion, R 1 represents a C 1-6 alkyl group or a benzyl group, R 2 represents a C 1-6 alkyl group or -C(C n H 2n O) q -H, R 3 represents -(C m H 2m O) r -H, R 4 represents -(C p H 2p O) s -H or -C t H 2t -Y-COR 5 , each of n, m, p and t is an integer of 2 to 4, each of q, r and s is an integer of 1 to 5, Y represents -O- or -NH-, and R 5 represents a C 7-35 alkyl or alkenyl group, and R 6 represents a C 7-35 alkyl or alkenyl group.
