本发明公开了一种甲醇汽油稳定剂,由2-辛胺18.0%~31.0%,N-叔丁基哌嗪15.0%~29.5%,4-N-丁氧基苯甲腈15.0%~24.5%,苯氧乙酸烯丙酯13.0%~24.0%,1,3-丙酮二羧酸二乙酯10.0%~20.5%,3-二甲基氨基苯甲醚9.0%~19.5%混合组成。在调制甲醇汽油前,先在甲醇中加入0.4%~0.8%本发明稳定剂混合均匀,常温下超声处理后再进行调制甲醇汽油的后续流程。使用本发明稳定剂的甲醇汽油存储稳定性改善效果显著,遇水抗相分离性能明显提
The present invention discloses a methanol gasoline stabilizer comprising 18.0% to 31.0% of 2-octylamine, 15.0% to 29.5% of N-tert-butylpiperazine, 15.0% to 24.5% of 4- 13.0% to 24.0% of allyl phenoxyacetate, 10.0% to 20.5% of diethyl 1,3-propanedicarboxylate and 9.0% to 19.5% of 3-dimethylaminoanisole. Before the modulation of methanol gasoline, methanol is first added 0.4% ~ 0.8% of the stabilizer of the present invention, and the mixture is uniformly sonicated at room temperature, followed by subsequent preparation of methanol gasoline. The use of the stabilizer of the present invention has the effect of improving the storage stability of methanol gasoline and obviously improving the anti-phase separation property when in contact with water
