Sulfuric acid amine salt, sulfonic acid amine salt, production thereof and softener composition

摘要

Provided is a process for preparing a sulfuric acid amine salt (I) represented by the formula (I), which is a neutralization compound between a sulfated compound having a long chain alkyl or alkenyl group and an amine having a long chain alkyl or alkenyl group, useful as softener.; wherein R³¹ is a linear or branched C_18-36 alkyl or alkenyl group, or a group represented by the formula R³⁶—(OA)_n- (wherein R³⁶ is a linear or branched C_12-36 alkyl or alkenyl group, OA is an oxyalkylene group having 2 to 4 carbon atoms and n is a number of from 0.1 to 10 on average), R³² is a is a linear or branched C_10-36 alkyl or alkenyl group, X is —CONH—, —NHCO—, —COO— or —OCO—, R³³ is a linear or branched C_1-6 alkylene group, R³⁴ is a linear or branched C_1-6 alkyl or hydroxyalkyl group, or a group represented by R⁵—[B—R⁶]_b—, R³⁵ is a linear or branched C_1-6 alkyl or hydroxyalkyl group, wherein R⁵ is a linear or branched C_10-36 alkyl or alkenyl group, R⁶ is a linear or branched C_1-6 alkylene group, B is a group selected from the group consisting of —COO—, —OCO—, —CONH— and —NHCO—, b is a number of 0 or 1 and m is a number of 0 or 1. A sulfonic acid amine salt may be obtained.
