Selective ultraviolet photolysis using either a KrF excimer laser or an unfiltered mercury arc lamp has been used to reduce substantially the phosgene impurity in a binary mixture of boron trichloride and phosgene. Infrared spectroscopic analysis of the sample before and after irradiation shows that it is possible to highly purify commercially available boron trichloride with this technique.
