Method for removal of phosgene from boron trichloride. [DOE patent application; mercury arc lamp]

Patent ·
OSTI ID:5192990
Selective ultraviolet photolysis using an unfiltered mercury arc lamp has been used to substantially reduce the phosgene impurity in a mixture of boron trichloride and phosgene. Infrared spectrophotometric analysis of the sample before and after irradiation shows that it is possible to highly purify commercially available boron trichloride with this method.
