摘要:十二醇经丙氧基化、磷酸酯化及中和反应合成了环氧丙烷(PO)平均加成数(p)为 3、6、9 的 extended
表面活性剂单十二烷基聚氧丙烯醚磷酸酯钠(C 12 P p P)。采用 FTIR、ESI-MS 表征了其结构。测试了其 Krafft 点
(T K )、耐电解质性、表面张力、发泡力、乳化力、润湿力和去污力,并与单十二烷基磷酸酯钾(MAPK)对比。
结果表明,C 12 P p P 的发泡力、乳化力、润湿力和去污性能均优于 MAPK;其 T K < 0 ℃,具有优秀的低温水溶性,
克服了 MAPK 的钠盐形式不能低温水溶的缺点。同时,合成的 C 12 P p P 的钙离子抗性高于 MAPK 5~8 倍,其耐
电解质性明显改善。另外,其对蛋白和皮脂的去污力与 MAPK 大致相同,推测与 MAPK 具有相近的低刺激性,
可以替代 MAPK 用于个人清洁和护理用品中。

Abstract: A series of extended surfactants (e-surfactants), sodium monododecyl polyoxypropylene
phosphates (C 12P pP) with propylene oxide (PO) average addition number (p) (p=3, 6, 9) were synthesized
from dodecyl alcohol by propoxylation and phosphorylation followed by neutralization. These e-surfactants
were characterized by FTIR and ESI-MS. The properties of C 12P pP, such as Krafft point (T K),
electrolyte-tolerance, surface tension, foamability, emulsifying power, wetting power and detergency were
tested and compared with those of monododecyl phosphate potassium salt (MAPK). The results showed
that these e-surfactants exhibited better foamability, emulsifying power, wetting power and detergency than
those of MAPK. Due to their T K < 0 ℃, the C 12P pP surfactants demonstrated excellent low-temperature
water solubility, which overcomes the shortcomings of sodium counterpart of MAPK insoluble at low
temperature. At the same time, the C 12P pP surfactants showed better calcium-tolerance, which was 5~8
times greater than that of MAPK. The C 12P pP surfactants almost had the same detergency for protein and
sebum soiled swatches as MAPK. Therefore, the synthesized C 12P pP surfactants have the similar low
irritation to MAPK and are able to replace MAPK in personal care and toiletries products.
