结果表明，对碘苯与丙烯酸正丁酯的Heck反应的催化性能，未改性催化剂基本没有活性，而改性后，10%Cu/5%KF/ZnO、20%Cu/10%KF/ZnO催化剂的催化转化率为100%和反式异构体的选择性为98%以上。

The results showed that under 200 W power, in the present of various alkalis, e.g. Na2CO3, NaF, KF, NaHCO3, and DMF-H2O (V∶V=5∶3) used as solvent, PVC-TETA-Pd could catalyze sodium tetraphenylborate to react quantificationally with iodobenzene in 20 min without inert gas protection, and all the phenyl g...

实验发现：在微波功率为200W时，在Na2CO3，NaF，KF，NaHCO3等多种碱的存在下，以DMF的水溶液(V∶V=5∶3)为溶剂，在无惰性气体保护下，PVC-TETA-Pd催化四苯硼钠与碘代苯在20min内即可定量反应，与常规加热方式相比，节省了大量时间；同时也证明了四苯硼钠的四个苯基均可参与Suzuki偶联反应；该催化剂回收再利用3次后，仍具有较高的催化活性。

One route was that the amino-groups on the silica gel were transformed to tertiary amines by Eschweiler-clarke reaction that amine-groups react with formaldehyde and methanoic acid to prepare tertiary amines; the silica gel intermediates with tertiary amine groups reacted with chorohydrocarbons to prepare insoluble silica gel quaternary ammonium salt bactericides. Another route was that the amino-groups on the silica gel reacted with excessive chlorohexadecane; the preparing intermediates were quaternized with iodomethane to obtain insoluble silica gel quaternary ammonium salt bactericides.

一条路线是根据埃施韦勒-克拉克(Eschweiler-clarke)胺甲基化反应，进行胺基叔胺化反应，制成带有叔胺官能团的硅胶中间体，此中间体上的叔胺与卤代烷反应生成杀菌活性官能团季铵盐，制成硅胶类水不溶性季铵盐杀菌剂；另一条路线是带有胺反应活性中心的硅胶与过量正氯代十六烷反应，得到的中间体再用碘甲烷季铵化，得到最终产品——水不溶性季铵盐杀菌剂。

The thermoinduced coloration system of fluorane/iodonium salt has been investigated. The kinatic studies of thermoinduced color development reaction in polymer film was performed. It was found that two different phenomena appeared in the relationship between reaction rate constant and temperature. A very low value of k〓(0〓mol〓·l·s〓) and very high energy of activation E〓(149 KJ·mol〓) observed in the region of low temperature, whereas a larger value of k〓(1~10 mol〓·1·s〓) and smaller energy of activation (E〓33 KJ·mol〓) displayed in the region of high temperature of 150℃.

研究了荧烷/碘鎓盐热致显色反应体系，进行了分子膜中热生色反应动力学的研究，发现热生色速度常数k〓和温度关系呈现二种不同情况：在低温区，k〓值很小（＜10〓mol·1·s），活化能很大（E〓=149KJ·mol〓）；而在高温区，k〓值较大（1~10〓mol·1·s），活化能较低（E〓=33KJ·mol〓），它们的转折点位于温度（T〓=119℃），表明高于T〓是进行热致显色反应的重要条件；考虑到它们用作热记录介质的可能，研究了熔融状态中热生色反应。
