The exchange of boron between BF₃(g) and BF₃∙phenol (1) was studied. The single-stage isotopic fractionation factor varied according to the equation, logα= (10.315/T) -0.02423, over the temperature range -8°C to 37°C. B¹⁰ is concentrated in the liquid phase. Vapor pressure measurements of dilute and concentrated solutions of BF₃ in phenol were made at various temperatures from -10°C to 40°C. The freezing point of the BF₃∙phenol complex was approximately -15°C; that for the BF₃∙phenol, -5°C.
