A series of α unsaturated ketones and esters have been synthesized by Knoevenagel reaction of aldehyde with carbonyl compounds which have active methylene group in the presence of tellurium (ⅳ) chloride in excellent yields .

用 TeCl4催化含有活泼亚甲基的羰基化合物与醛的Knoevenagel反应，合成了一系列α，β－不饱和酮或酯，收率最高达95%。

Novel rare-earth contained bismuth telluride thermoelectric materials were prepared by solvothermal synthesis at 180 ℃ using bismuth chloride tellurium powder and lanthanum chloride or oxide as starting materials and the following hot uniaxial pressing ( HUP ) 400 ℃ at 50 () MPa for 1h .

以氯化铋、 碲粉、 氯化镧或氧化镧为原料，采用180℃溶剂热合成和400℃、50MPa、1h热压技术制备了含稀土的新型Bi2Te3基热电材料。
