以二苯醚和系列α-烯烃为原料合成出二烷基二苯醚,经氯磺酸磺化和NaOH溶液中和,制得系列二烷基二苯醚单磺酸钠(MAMS)阴离子表面活性剂。测定了表面活性剂溶液与烷烃之间在不同条件下的界面张力,并讨论了盐度、活性剂浓度和烷烃链长对表面张力的影响。
The dialkyl diphenyl ether was synthesized from diphenyl ether and series α-olefins. After neutralization with sodium chlorosulfonate and NaOH solution, a series of dialkyl diphenyl ether monosulfonate (MAMS) anionic surface Active agent. The interfacial tension between surfactant solution and alkane was measured under different conditions. The effects of salinity, active agent concentration and alkane chain length on surface tension were also discussed.
