摘要：

以双酚A、甲醛和二乙烯三胺为原料，在70 ℃下反应60 min，再在120 ℃，1.33 kPa下脱水缩合得到酚胺树脂，然后以酚胺树脂为起始剂，与PO、EO反应合成了6种具有十八分支的PAE聚醚破乳剂。测定了所合成聚醚的表面张力及紫外吸收光谱。结果表明，PAE聚醚破乳剂降低表面张力的能力随EO质量分数的降低和起始剂与PO质量比的升高而增强；降低临界胶团浓度的能力随起始剂与PO质量比的增加及EO质量分数的降低而增强。室内评价表明，PAE聚醚破乳剂的最终脱水率随EO质量分数增加而升高，起始剂与PO质量比高的破乳剂脱水速度快。PAE84在40 ℃，加量20 mg/L时，15 min脱水率即达到80%，而相同条件下SP169基本无破乳效果。

Abstract:

The phenol-amine resin was synthesized through dehydration condensation reaction of bisphenol A, diethylenetriamine and formaldehyde at reaction temperature 70 ℃, reaction time 60 min and the post treatment was 120 ℃, 1.33 kPa. PAE polyether demulsifiers with different EO mass fraction and mass ratio of initiator to PO were synthesized through reactions with different proportions of propylene oxide and ethylene oxide using phenol-amine resin as initiator. The characterization of PAE demulsifiers was studied by surface tension measurement and UV-vis spectra method. The results show that within low concentrations the ability of decreasing surface tension increased with decreasing EO mass fraction and increasing mass ratio of initiator to PO; the efficiency of decreasing surface tension increases with increasing mass ratio of initiator to PO and decreasing EO mass fraction. From the demulsification experiments a conclusion has been drawn that the final dehydration rate of demulsifiers increased with increasing mass fraction of EO; the speed of reaching dehydration platform is faster for the demulsifier with high mass ratio of initiator to PO. Dehydration rate of 80% is observed at 40 ℃,15 min and dosage 20 mg/L for PAE84, and there is no demulsification effect for SP169 at the same condition.
