中文摘要:
      以腰果酚聚氧乙烯醚(BGF-10)和丙烯酸(AA)为原料,通过直接酯化的方法在对苯二酚为阻聚剂,对甲苯磺酸催化作用下,合成了丙烯酸腰果酚聚醚酯(BGFAA),探究了反应物物料比n(AA):n(BGF-10)、反应温度、反应时间、催化剂用量、阻聚剂用量对酯化率的影响,并在此基础上采用响应面优化法对酯化反应工艺条件进行了优化。得出合成BGFAA的最佳工艺条件为:在反应温度127℃、反应时间5.2h、n(AA):n(BGF-10)=1.6:1、阻聚剂用量0.6%(占反应物总质量)、催化剂用量5%(同上)时,酯化率高达93.23%,结构经红外光谱和核磁共振进行了表征确认;在偶氮二异丁腈引发作用下将自制BGFAA和丙烯酸(AA)引发聚合制备了新型稠油破乳剂(BGFAA)n,并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,当破乳温度为60℃、破乳时间为2.5h、破乳剂用量500mg/mL时,脱水率高达86.8%、脱出污水含油吸光度为1.05,表明(BGFAA)n在稠油乳液中具有脱水率高、脱出污水含油低水质清澈的优势。
英文摘要:
      the use of cardanol polyoxyethylene ether (BGF-10) and acrylic acid (AA) as raw materials, through the direct esterification method, hydroquinone phenolic polymerization was synthesized under the catalysis of hydroquinone as a polymerization inhibitor and p-toluenesulfonic acid. The ether ester (BGFAA) was used to investigate the effect of reactant material ratio n(AA):n(BGF-10), reaction temperature, reaction time, amount of catalyst and amount of polymerization inhibitor on esterification rate. The response surface optimization method optimizes the esterification reaction conditions. The optimum conditions for the synthesis of BGFAA are as follows: reaction temperature 127 ° C, reaction time 5.2 h, n (AA): n (BGF-10) = 1.6:1, polymerization inhibitor dosage 0.6% (accounting for the total mass of the reactants) When the amount of catalyst is 5% (same as above), the esterification rate is as high as 93.23%, and the structure is confirmed by infrared spectroscopy and nuclear magnetic resonance. A new type of heavy oil demulsifier (BGFAA) n was prepared by initiating polymerization of self-made BGFAA and acrylic acid (AA) under the action of azobisisobutyronitrile. The dehydration rate and the oil absorbance of the dewatered wastewater were used as indicators to study the effect of Chen Zhuang. The demulsification dehydration performance of the oil w/o emulsion, when the demulsification temperature is 60 ° C, the demulsification time is 2.5 h, the demulsifier dosage is 500 mg/mL, the dehydration rate is as high as 86.8%, and the oil absorption absorbance of the dewatered sewage is 1.05, which showed that (BGFAA)n had the advantages of high dehydration rate, low oil content of dehydrated sewage and clear water quality.
