摘要/Abstract

摘要： 以腰果酚、甲醛和多乙烯多胺为原料合成腰果酚胺树脂起始剂,再与环氧乙烷(EO)和环氧丙烷(PO) 聚合,合成了分子质量各异的4种腰果酚胺树脂型嵌段聚醚(CPAE)表面活性剂。采用FT-IR对其结构进行了表征,采用表面张力法和瓶试法分别研究了系列CPAE 的表面性能和破乳性能。结果表明,随着EO 含量的增加,CPAE的临界胶束质量浓度(cmc)及此时的表面张力(γcmc)增加;随着相对分子质量的增加,cmc及γcmc降低。随着CPAE浓度的增加,CPAE水溶液的界面张力降低,脱水率增大。在80mg/L,35 ℃,100min的条件下,CPAE的脱水率即可达到70%以上,破乳效果远优于商用破乳剂SP169,BP169及TA1031。

Abstract: Two phenol-amine resin were synthesized using cardanol as raw materials,and then four amphiphilicc ardanol based phenol-amine resin block polyethers(CPAE)of different molecular weight were further synthesized using phenolamine resin as initiator through addition reaction with epoxyethane and epoxypropane respectively.Four CPAE were characterizad byFT-IR.The surface tension and interfacial tension were measured,and demulsification performance were studied using bottle test.The results show that the cmc and γcmc of CPAE increased with the increasing of EO content.The interfacial tension of CPAE aqueous decreased and dewatering rate increased as the concentration increased.Under the conditions of 80 mg/L,35 ℃ and 100 min,the dewatering rates of four CPAE are all above 70%,far superior to that of commercial demulsifiers SP169,BP169 and TA1031.
