Abstract
A process for the conversion of boron trifluoride dimethyl ether complex to boron trifluoride dialkyl ether complex substantially free of dimethyl ether impurities, which comprises reacting the boron trifluoride-dimethyl ether complex, in the liquid phase, in the presence of dialkyl ether wherein at least one of the alkyl groups contains at least two carbon atoms, in a restricted vapor equilibration region, while simultaneously sweeping the said vapor equilibration region with a substantially inert gas, and heating to distill off the dimethyl ether. High purity of the boron trifluoride dialkyl ether complex is attained with this method, with only minimal traces of the boron trifluoride dimethyl ether complex, dimethyl ether remaining. The preferred product is boron trifluoride diethyl ether.
