Study of the reaction between boron trifluoride methanol complex and sodium methoxide

Abstract

The reaction between boron trifluoride methanol complex and sodium methoxide in methanol solution was investigated using conductivity as the reaction indicator. The reaction conditions were examined and a mechanism of this reaction was proposed. Moreover, proper reaction conditions were proposed for boric acid preparation using this reaction.

Graphical Abstract

Boron trifluoride methanol complex was added to sodium methoxide at 65 and 25 °C, and the reaction time was 18 and 6 h, respectively. This figure indicates that the feeding stage is the controlling step of the whole reaction.
