By means of GC, GC-MS, GC-IR, IR, H1-NMR,the reaction products were investigated and the results showed that there are camphene, limoneneN terpinolene, Me a -fenchyl ether, Me -terpinyl ether, Me bornyl ether and Me isobornyl ether containing in the products,and the content of the main product Me a -terpinyl ether is up to 42.5%,the selectivity is 44.7%.

采用GC、GC-IR、GC-MS、IR、H~1-NMR等对反应产物进行定量和定性分析，结果表明：微波辐射下α-蒎烯与甲醇的反应产物含有莰烯、柠檬烯、α-小茴香甲醚、异松油烯、异菠基甲醚、菠基甲醚、α-松油基甲醚等，在较好的工艺条件下，主产物α-松油基甲醚的得率为42.5％，选择性为44.7％。

The method is realized by that polyether ether ketone is added into concentrated sulfuric acid to carry out sulfonation reaction, thereby obtaining sulfonated polyether ether ketone, then the sulfonated polyether ether ketone is dissolved in organic solvent, N, N (1)-Carbonyldiimidazole is added to stir for one to three hours, coupling agent is mixed for stirring the reaction for 1.5 to 4 hours, then inorganic crosslinking agent is mixed to react under the temperature of 50 to 80 DEG C. Proton conductors are mixed to continue getting the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors under the temperature. Finally the proton exchange membrane for a direct methanol fuel cell is obtained by that the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors is/are processed through membrane forming, drying and exuviation.

该方法首先将聚醚醚酮加入浓硫酸中进行磺化反应得到磺化聚醚醚酮；然后将磺化聚醚醚酮溶于有机溶剂中，加入N，N′-羰基二咪唑搅拌1～3小时后加入偶联剂搅拌反应1.5～4小时，再加入无机交联剂在50～80℃下反应，然后加入质子导体继续在此温度下反应得到磺化聚醚醚酮/无机交联剂/质子导体的混合溶液；最后将磺化聚醚醚酮/无机交联剂/质子导体的混合物溶液成膜，干燥，脱膜即得到所述的直接甲醇燃料电池用质子交换膜。

The preparation of avermyctin emulsions in water was achieved by mixing the surfactants polyoxyethylene (10) octylphenyl ether (OP10), polyoxyethylene styrenated phenol ether (602), and polyoxyethylene (40) castor oil ether (EL-40) with polyoxyethylene (20) castor oil ether (EL-20), separatively. Emulsion stability was investigated by analyzing the hydrophile-lipophile balance, critical micelle concentration, and surface tension. Then, the surfactants of polyoxyethylene polyoxypropylene styrenated phenol ether (1601), block copolymer (L64), and octyl phenyl polyoxyethylene phosphonate were added to the emulsion made by blending EL-40 and EL-20, separatively. The stability of the emulsions was investigated further and discussed in terms of droplet size, surface tension, and zeta potential.

首先将辛基酚聚氧乙烯醚(OP10)、苯乙烯基酚聚氧乙烯醚(602)和蓖麻油聚氧乙烯(40)醚(EL-40)分别与蓖麻油聚氧乙烯(20)醚(EL-20)复配制备阿维菌素水乳剂，从亲水亲油平衡值、临界胶束浓度、表面张力等方面分析了二元表面活性剂复配对乳液稳定性的影响；其次，在EL-40与EL-20复配基础上，将苯乙烯基酚聚氧乙烯聚氧丙烯醚(1601)，嵌段共聚物(L64)和辛基酚聚氧乙烯醚磷酸酯分别添加到乳液中，从粒径、表面张力和zeta电势等方面考察三元表面活性剂复配对乳液稳定性的影响。
