Abstract
An alkyl borate ester of the formula B(OR)3, where R is an alkyl radical containing 1, 2 or 3 carbon atoms, is produced by heating a mixture of a boron trifluoride etherate with an alkali metal alkoxide in the presence of an inert solvent, the alkyl radical of the alkoxide being the radical R desired in the product, and the boiling points of the inert solvent and the ester produced differing by at least about 20 DEG C. The inert solvent should not either react chemically with or form an azeotropic mixture with the ester. A hydrocarbon solvent such as xylene, toluene, benzene, cyclohexane, n-decane or pentane is suitable. If the solvent has a b.p. lower than the ester, the reaction may be carried out under reflux and the solvent may be distilled off on completion of the reaction. If the b.p. of the solvent is higher than that of the ester, the latter may be distilled off continuously as produced and fresh reactants may be added continuously to the reaction mixture. A boron fluoride diethyl etherate and a sodium alkoxide are the preferred reactants. Alkyl borate esters enriched in the B10 isotope may be obtained using a boron fluoride etherate enriched in the B10 isotope.
