SUMMARY
The discussion focuses on the removal of oxygen from boron powders through milling in methanol, which facilitates the formation of boron esters, specifically trimethyl borate. It is established that B2O3 reacts with methanol, producing boron esters that volatilize during solvent evaporation under reduced pressure. However, the formation of these esters is significantly enhanced in the presence of an acid catalyst, such as sulfuric acid. The boiling point of trimethyl borate is noted as 69°C at atmospheric pressure.
