PREPARATION OF NITROGEN TRIFLUORIDE

摘要

PREPARATION OF NITROGEN TRIFLUORIDE Nitrogen triflouride is prepared by passing elemental fluorine in intimate contact with liquid phase ammonium acid fluoride maintained at a temperature above its melting point but below about 400.degree.F for a time sufficient to effect reaction. Generally, ammonia is injected into the ammonium acid fluoride along with the fluorine to maintain a molar ratio of by-product hydrogen fluoride to ammonia of approximately 2.0 to 2.5.
