Abstract

Abstract:

A kind of photosensitive anionic surfactant was synthesized using 4-butylaniline, ethyl bromacetate andphenol. Its structure was identified by ¹HNMR and its properties were also measured. It was found that photoisomerization of the surfactant occurred under the irradiation of ultraviolet light and its time to make balance was about 40 min. After the irradiation of ultraviolet light, the values of cmc, γ_cmc and A_min increased and the values of Г_max, pC₂₀ and the contact angle on thecalcite surface decreased.

Key words: photosensitive, azobenzene, surfactant, photoisomerization, surface tension, contact angle
