dibasic aluminum monorosinate

A new unsymmetrical Bolaform surfactant,namely disodium sulfodehydroabietate(DSDA)was synthesized by sulfonation of dehydroabietic acid followed by neutralization,and its structure was characterized by FT-IR,1H NMR and MS.

以脱氢松香酸为原料,经磺化、中和反应合成了一种非对称Bola型表面活性剂磺化脱氢松香酸二钠盐(DSDA),利用FT-IR、1HNMR及MS对目标产物结构进行确证,采用表面张力法确定了DSDA在303。
