三溴化硼11

Boron11 Tribromide


产品介绍 Product introduction

        三溴化硼11（B11Br3）在常温常压下为具有刺鼻恶臭的无色发烟液体，能放出刺激性蒸气，遇水及受热分解放出有毒气体HBr。不溶于水，与乙醇、醚等的氧化物不生成附加化合物，但与胺类、磷烷类作用生成多种附加化合物。三溴化硼能与许多电子对给予体（如含磷、氮、砷、氧、硫和卤素等物质）反应生成酯位化合物。高纯三溴化硼11在半导体工业用作掺杂源。
Boron tribromide(BBr3) is a kind of colorless fuming liquid with pungent odor at normal temperature and pressure. BBr3 can release irritating steam, it releases toxic gas HBr when it is heated or exposed to water. BBr3 is insoluble in water, it does not form additional compound with oxides such as ethanol and ether, but it reacts with amines and phosphorane to form a variety of additional compounds. Boron tribromide can react with a lot of electron pair donor (such as phosphorus, nitrogen, arsenic, oxygen, sulfur and halogen) to form ester compounds. High pure boron11 tribromide is used as doping source in semiconductor industry.
