Abstract:	An attempt was made to prepare pure methyl borate by an ester interchange using a high-boiling alkyl borate in combination with methyl benzoate or methyl phthalate. The product, assumed to be methyl borate, boiled at about 70°C., which is 5° higher than the expected boiling point, and analyzed at 88 to 95%. Various catalysts, such as hydrochloric acid, sodium methoxide, p-toluene sulfonic acid, aluminum isopropoxide, and aluminum chloride, were tried before magnesium-aluminum ethoxide was chosen as the best catalyst for this particular tranesterification reaction.
