Recent development in research of tin-containing catalysts used in Baeyer-Villiger oxidation was reviewed.

综述了近年来含锡催化剂在Baeyer-Villiger反应(酮转化为相应的酯或内酯的反应)中的应用研究进展,分别介绍了Sn-β沸石、Sn-MCM-41、水滑石负载锡、坡缕石负载锡等非均相催化剂及锡的全氟化辛烷磺酰胺配合物、苯胺和苯甲醇取代的有机锡配合物等均相催化剂。

On the basis of the detailed and truthful geologic survey data in field,studied petrography,petrochemistry,geochemistry characteristics;it is considered that Dashizhai rock bodies belong to tin-bearing granite It contributes the new data for tin prospecting in the study area.

在近期开展的1/5万矿调项目工作中,围绕大石寨岩体的周边地区,新发现了数处与锡有关的多金属矿点,本文在对该岩体进行详实的野外地质调查基础上,详细研究了大石寨岩体岩石学特征、岩石化学特征、地球化学特征,揭示出大石寨岩体为含锡花岗岩,从而为该地区寻找与花岗岩相关的锡矿产提供了新的资料。

Located in the eastern part of Guangdong Province, the Tashan tin-bearing granoporphyry oc-curs as a dlke wlth an emplacement age of 138 Ma.

粤东塌山含锡花岗斑岩以岩脉产出，侵位年龄138Ma，含不等数量的原生铝质矿物，如红柱石、铁铝榴石、铁叶云母和白云母等。
