PROCEDURE

实验过程

2,6-Diisopropylphenol (20 kg, FW (formula weight)=178, 112 mol, 1 equiv.) is reacted with bromochloromethane (347 kg, FW=129, 2,682 mol, 24 equiv.) and sodium hydroxide (11 kg, FW=40, 280 mol, 2.5 equiv.) in tetrahydrofuran (108 kg, FW=72, 1,498 mol, 13.3 equiv.) at reflux for approximately 1.5 hours. After cooling to 20° C., the reaction mixture is quenched with water (87 kg). The organic layer is collected and washed with 15% sodium chloride aqueous solution (78 kg) twice. The organic layer is collected again after the layer separation, and the solvents are distilled from the organic layer to afford a crude oil. The crude oil is distilled by simple distillation to yield a purified chloromethyl(2,6-diisopropylphenyl)ether (FW=227) as a light yellow oil.
