tellurium chloride

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。

A series of α,β 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%。
