The best operational parameters were that the reaction temperature was 105℃, the reaction time was 3 hours, the mixture ratio of n: n=1:2.79, using N,N-dimethyl benzylamine as catalyst, and 2,6-Di-tert-buthyl-p-cresol as inhibitor.

结果表明，合成TGICA的最优化条件为：n/n=l：2.79；催化剂为N，N－二甲基苯胺；阻聚剂为2，6－二叔丁基对甲酚；反应温度(105±2)℃；反应时间3h。丙烯酸的转化率可达到99.7%。

CuS and CdS nano-particulate films were obtained with these two methods, and some interesting phenomena were observed: under the Gibbs film formed by CTAB, CuS nano-rods were obtained at the oil/water interface, and disklike aggregates of CdS nano-crystals were obtained at both the air/water and oil/water interfaces; under the Langmuir film formed by NaAOT at air/water interface, disk-like aggregates of CdS were also obtained.

利用此两种反应技术，制备了CuS和CdS颗粒膜，并研究了它们的一些光电性质；在Gibbs膜下，得到了棒状CuS纳米晶。由发现的表面活性剂形成的带状物，提出棒状CuS晶体是以带状聚集体为模板形成的；在液-液、气-液界面Gibbs膜下反应中，发现CdS纳米颗粒的盘状聚集体的形成，这是由于表面活性剂在界面上形成的二维胶束而造成的；在气-液界面上Langmuir下的反应中，也发现CdS盘状晶体的生成。
