The addition of 1, 2-Butylene oxide to laurylamine was investigated. It was found that the tertiary amine, N, N-bis (2-oxybutyl) laurylamine, was formed by the reaction without catalyst. A series of polyoxyethylene derivatives of laurylamine-butylene oxide 2 moles adduct were prepared and the changes in their surface activities in aq. and 1N-HCl solutions, such as surface tensions, foaming properties, wetting powers, dispersing and emulsifying powers, by the difference in the numbers of moles of butylene oxide and ethylene oxide, were discussed. In 1N-HCl solution, the wetting power of the butylene oxide adduct is superior, while the surface tension, foaming property and emulsifying power are inferior than those of laurylamine. The wetting power and dispersing power of the butylene oxide·ethylene oxide adducts are excellent in both aq. and 1N-HCl solutions.
