Page/Page column 19-20, (2008/06/13)
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 C18-36 alkyl or alkenyl group, or a group represented by the formula R36-(OA)n- (wherein R36 is a linear or branched C12-36 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 C10-36alkyl or alkenyl group, X is -CONH-, -NHCO-, -COO- or -OCO-, R33 is a linear or branched C1-6 alkylene group, R34 is a linear or branched C1-6 alkyl or hydroxyalkyl group, or a group represented by R5 - [B-R6]b-, R35 is a linear or branched C1-6 alkyl or hydroxyalkyl group, wherein R5 is a linear or branched C10-36 alkyl or alkenyl group, R6 is a linear or branched C1-6 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.

Lithium, sodium, potassium, cesium, and ammonium palmityl sulfates were prepared by sulfination of n-hexadecanol, followed by treatment with the corresponding alkali carbonates; selectively deuterated palmityl sulfates were also synthesized to aid the assignment of certain vibrational modes.The infrared and Raman spectra of the polycrystalline solids were interpreted and discussed in terms of acyl chain and head group vibrations.Spectral evidence is presented for the existence of diferent solid polymorphic forms.
