ABSTRACT:
An improved method for the transesterification of secondary alcohol borate esters with methanol, the improvement comprising separating a portion of the extractive distillation column overhead as a reflux stream and returning said reflux stream to the extractive distillation column between points located at or below the point at which the borate ester feed is introduced to the column and at or above the point at which methanol is introduced to the column, thus reducing the amount of boron-containing compounds in the crude secondary alcohol product stream.
