四氟硼酸亚硝

四氟硼酸亚硝用途

1.胺类的亚硝化剂。制芳香重氮硼酸盐。仲胺生成亚硝胺。酰胺、磺酰胺在温和条件下生成相当的酸。苯、甲苯与伯胺在其作用下烷化。与伯、仲烯在乙肪中生成咪哩盐。氧化节醇成醛。分解苄酯。

四氟硼酸亚硝制备

1.注意1使用氟化氢和三氟化硼有危险，整个操作应在通风橱中进行，有关注意事项见四氟硼酸硝翁
在聚乙烯反应器上安装搅拌器、气休导入管(伸到液面下)和气休导出管，气休导入管前接一支T形管用以通入千燥氮气的慢气流。反应器中盛900毫升干燥的硝基甲烷，冷却到一20℃。在搅拌下，依次慢慢地加入60克(3.0摩尔)无水氟化氢、204克(3.0摩尔)三氟化硼和276克(6.0摩尔)二氧化氮。每一种试剂的加入速度都要控制使温度保持低于0℃。加二氧化氮时，生成氟硼酸盐的沉淀。在干燥箱中过滤，收集白色沉淀。连续地用3份了5毫升硝基甲烷和3份75毫升四氯化碳洗涤，在50一100℃的真空烘箱中干燥过夜。产量为341克97%。
