反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Boric acid (1 mole) and 2-methyl-2,4-pentanediol (1 mole) were placed in a reaction vessel with 1000 ml of benzene and the mixture refluxed until 2 moles of water were removed. Evaporation of the benzene at reduced pressure gave a liquid which slowly crystallized to give a white solid mp 73°-75° C [literature mp 69°-70° C, H. Steinberg and D. L. Hunter, Ind. & Eng.

実験手順: 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. equipped with stirrer Marcusson apparatus and reflux condenser The reaction mixture is heated up to its is kept at that temperature for a 4-hour period
