三氟化砷制备

制法1 如图所示三氟化砷的制备装置

用三氧化二砷制备 As₂O₃+6HF→2AsF₃+3H₂O

把三氧化二砷装入如图所示的铁制蒸馏器中，在140℃油浴中加热，同时通入无水氟化氢气体。用冰盐冷却剂将蒸馏出来的AsF₃冷却到18℃。利用从冷凝器馏出的液体AsF₃量来调节氟化氢气体的通入量。停止通入氟化氢气体后，将10%(体积分数)的硫酸加到粗AsF₃中，将接受器直接用作蒸馏烧瓶进行蒸馏。AsF₃的主要馏分在50～85℃之间馏出。以As₂O₃计，收率为80%（图示）。

制法2 As₂O₃+3CaF₂+3H₂SO₄→2AsF₃+3CaSO₄+3H₂O

在铅制蒸馏罐中装入50g As₂O₃及50g CaF₂，并加入200g相对密度为1.84的浓硫酸进行蒸馏。AsF₃以无色液体馏出。在连接处用聚四氟乙烯润滑脂。
