摘要：以腰果酚聚氧乙烯醚（BGF-10）和丙烯酸（AA）为原料，通过直接酯化法合成了丙烯酸腰果酚聚醚酯
（BGFAA）。考察了不同因素对酯化率的影响，并采用响应面优化法对酯化工艺进行了优化。得出合成 BGFAA
的最佳工艺条件为：在反应温度 127 ℃、反应时间 5.2 h、n（AA）∶ n（BGF-10）= 1.6∶1.0、阻聚剂用量 0.6%
1
（以 BGF-10 与 AA 总质量为基准，下同）、催化剂用量 5%时，酯化率达到 93.23%。BGFAA 结构经 FTIR、HNMR
进行了确证。将自制 BGFAA 和 AA 引发聚合制备了一种聚合物稠油破乳剂，以脱水率和脱出污水含油吸光度
为指标研究了其对陈庄稠油 W/O 乳液的破乳脱水性能。结果表明，当破乳温度为 60 ℃、破乳时间为 2.5 h、破
乳剂用量 500 mg/L 时，脱水率达到 86.8%，脱出污水含油吸光度为 1.05。与两种商用破乳剂相比，制备的破乳
剂具有脱水率高、脱出水质清澈的优势。

Abstract: Cardanol acrylate polyether ester (BGFAA) was synthesized from cardanol polyoxyethylene
ether (BGF-10) and acrylic acid (AA) by direct esterification. The effects of different factors on the
esterification rate were investigated, and the esterification process was optimized by response surface
methodology. The results showed that the optimum technological conditions for the synthesis of BGFAA
were obtained as follows: reaction temperature of 127 ℃, reaction time of 5.2 h, n(AA)∶n(BGF-10)=
1.6∶1.0, polymerization inhibitor dosage 0.6% (based on the total mass of BGF-10 and AA, the same below)
and catalyst dosage 5%. Under these conditions, the esterification rate reached 93.23%. The structure of
1
BGFAA was characterized by FTIR and HNMR. A novel polymer heavy oil demulsifier was prepared
using self-made BGFAA and AA as raw materials. The demulsification and dehydration performance of
W/O emulsion of Chen Zhuang heavy oil was studied by taking dehydration rate and oil absorbance of
dehydrated sewage as indexes. When the demulsification temperature was 60 ℃, the demulsification time
was 2.5 h, and the dosage of demulsifier was 500 mg/L, the dehydration rate reached 86.8% and the oil
absorbance of dehydrated sewage was 1.05. Compared with two commercial demulsifiers, the prepared
demulsifier has the advantages of high dehydration rate and clear water quality.
