Abstract
A series of sodium polyoxybutylated octyl, decyl, and lauryl phosphates was prepared by adding 1, 2-butylene oxide to the corresponding alcohols. The relation of their surface activities, such as surface tension, foaming properties, wetting power, dispersing power and emulsifying power, and the length of oxy-butylene chain was studied.
The surface tension of butylene oxide adducts is lower in the low concentration as compared with corresponding alkyl phosphates. Addition of butylene oxide generally improves the foaming power, wetting power, dispersing power and emulsifying power. The foam stability of all products is small.
