95 °C

Procedure

61.2 g of boric acid (1 mol) and 118.2 g of 2-methyl-2,4-pentanediol (1 mol) and 200 ml of heptane are charged to a reaction flask equipped with stirrer, Marcusson apparatus and reflux condenser. The reaction mixture is heated up to its reflux temperature (about 95° C.), with stirring, and is kept at that temperature for a 4-hour period.
