摘要：

以腰果酚为起始原料，合成了中间体腰果酚聚氧乙烯醚（CPE），进而在NaOH的催化作用下，由CPE和氯乙酸合成了系列腰果酚聚氧乙烯醚羧酸盐（CPEC）。 采用红外光谱和元素分析技术对产物的结构进行了表征，用表面张力法研究了CPEC的表面性能。 结果表明，该表面活性剂水溶液的临界胶束浓度(CMC）为9.30、8.50、8.10和7.71 mmol/L，相应的临界表面张力为28.38、28.60、30.40和30.00 mN/m。 根据Gibbs公式得出表面活性剂在溶液表面的最大吸附量为0.7087、0.7350、0.7195和0.7346 μmol/m2，表面活性剂的最小分子截面积为2.3439、2.2600、2.3087和2.2613 nm2。

Abstract:

Cashew phenol polyoxyethylene ethers(CPE) were synthesized from cashew phenol as raw materials. In the presence of sodium hydroxide as a catalyst, a series of cashew phenol polyoxyethylene ether carboxylates(CPEC) were synthesized with CPE and chloroacetic acid. The products were structurally confirmed by FT-IR and elemental analysis. Surface properties were determined by a surface tension method. The experimental results showed that when critical micelle concentrations(CMC) of the surfactants were 9.30, 8.50, 8.10 and 7.71 mmol/L, the corresponding surface tensions at CMC were 28.38, 28.60, 30.40 and 30.00 mN/m, respectively. By means of Gibbs formula, the maximum adsorption amounts of the surfactants were 0.7087, 0.7350, 0.7195 and 0.7346 μmol/m2, and the minimal molecular projective areas of them were 2.3439, 2.2600, 2.3087 and 2.2613 nm2, respectively on solution surface.

Key words: cashew phenol, cashew phenol polyoxyethylene ether carboxylate, surface activity property
