产品描述

Application

Sodium selenite can be used:
• In dehydrogenation of benzoins to benzils and, flavanones to flavones under thermal and microwave conditions.[6]
• As a catalyst along with cysteine or glutathione in the reductive debromination of vic-dibromides to alkenes.[7]
• To prepare bis(methylmercuric) selenide (BMS) by reacting with methylmercuric chloride and reduced glutathione or cysteine.[8]

亚硒酸钠是合成硒化锌 (ZnSe) 过程中常见的硒来源。[1]其被作合成硒化铋纳米复合材料、[2] 镍钴硒化物、[3] 硒纳米带 [4] 和 -硒纳米管的关键前体。[5]
