実験手順
To a solution of 50 g (1.25 mol) of NaOH in 1200 ml H2O was added 108 g (1 mol) of m-cresol freshly distilled and at 15° C. in one lot 117ml (1.5 mol) of epichlorohydrin. The emulsion was stirred at room temperature for 16 hours in a creased flask. The product was taken up in 1000 ml of toluene and washed with 500 ml water. Distillation yielded 135.7 g=82% of product, bp 61° C. (0.05 mm).
