摘要:      乙醇汽油是极具发展潜力的清洁可再生燃料,影响乙醇汽油推广应用的关键是它的稳定性问题。通过测定乙醇汽油混合物的浊点变化,考察了表面活性剂及助剂对含水乙醇汽油增溶性的影响。实验结果表明:异构醇类助剂对乙醇汽油的增溶性有较好的影响;复合助剂比单一助剂效果好,其中混合助剂异戊醇和异丁醇效果最好;乳化剂SP-80对含水乙醇汽油具有很好的增溶性,比异构醇类助剂效果好,并且随着加入量的增加,效果更加显著;乳化剂SP-80和助剂异戊醇复配效果最好,当SP-80体积分数为1.0%、异戊醇体积分数为1.0%时,乙醇汽油的相分离温度降为-35.0℃

Abstract: Ethanol-gasoline is a clean and reproducible fuel with potential of development, the key effects hydrated ethanol- gasoline blends' popularization and application is its stability. Through the test of hydrated ethanol-gasoline'cloud point change, hydrotropy of surfactant and cosolvent were investigated for hydrated ethanol-gasoline blends.The experimental results show that heterogeneous alcohols cosolvent has a better hydrotropy on ethanol- gasoline blends; Multiplex cosolvents is better than a single cosolvent, among whch the combination of isoamyl alcohol and isobutyl alcohol is the best. Emulsifier SP-80 to hydrated ethanol-gasoline has the better hydrotropy than heterogeneous alcohols cosolvent, and with the increased amount of it, the effect is more significant. Emulsifier SP-80 blends with additives isoamyl alcohol has the best effect, with the conditions: when SP-80 volume content is 1.0% and isoamyl alcohol volume content is 1.0%, ethanol and gasoline phase separation temperature dropped to -35.0 ℃.
