摘要:以双戊烯为原料,经催化异构及D-A加成合成了萜烯马来酸酐,萜烯马来酸酐再分别与不同分子质量的聚乙二醇(400,600,1 000,2 000,4 000)反应,合成了5种聚萜烯马来酸酐聚乙二醇酯高分子表面活性剂(Ⅰ~Ⅴ),用红外光谱仪和凝胶色谱仪对产物的结构进行了表征,并对其聚合度(DP)、临界胶束浓度(CMC),表面张力(γ_(CMC)),乳化性能(EP),泡沫性能(FP)和亲水亲油平衡值(HLB)等表面活性性能进行了研究。结果表明:产物Ⅰ、Ⅱ、Ⅲ、Ⅳ和Ⅴ的CMC值分别为6.5、2.1、2.7、3.3和5.5 g/L,γ_(CMC)分别为42.0、38.2、39.8、42.1和33.7 m N/m。随着聚乙二醇分子质量的增大,CMC及γ_(CMC)均呈现先减小后增大的趋势;DP先增大后减小,产物Ⅱ聚合度最大,为4.9;EP逐渐降低,产物Ⅰ乳化性能最好,达到780 s;HLB逐渐增大,亲水性增强。
The terpene maleic anhydride was synthesized by catalytic isomerization and D-A addition from dipentene. And then, the polymerized terpene maleic anhydride polyethelene glycol ester polymer surfactants( Ⅰ -Ⅴ ) were synthesized by the reactions of the terpene maleic anhydride and different polyethelene glycol(400,600, 1 000, 2 000, 4 000). The structures of surfactants were characterized by IR and GPC, respectively. The critical micelle concentration (CMC), surface tension (TcMc), emulsifying property(EP), foaming property (FP) and hydrophile-lipophile balance (HLB) value were evaluated. The results showed that CMC values of products I -V were 6. 5, 2. 1,2. 7, 3.3 and 5.5g/L, respectively, and the corresponding TcMc values were 42. 0, 38. 2, 39. 8, 42. 1,33.7mN/m. With the increment of molecular weight of polyethylene glycol,the CMC and γCMC decreased and then increased, while the emulsifying property decreased and hydrophile-lipophile balance value increased gradually.
