실험 절차

A 1,000-ml four-necked flask provided with a stirring machine, a thermometer, a dropping funnel, and a nitrogen-introducing pipe was mounted with a condenser to which a water scrubber had been connected, and then 2.0 mol (244 g) of 2,6-dimethylphenol, and 0.016 mol (1.5 g) of magnesium chloride were loaded into the resultant reactor. The atmosphere in the reactor was replaced with nitrogen and then its temperature was increased to 120° C. 1.0 Mole (153 g) of phosphorus oxychloride was dropped into the reactor at that temperature over 2 hours. After the completion of the dropping, the temperature was increased to 180° C. over 2 hours. Thus, di(2,6-xylyl)phosphorochloridate was obtained. The temperature in the flask was cooled to 20° C., and then 0.5 mol (55 g) of 1,3-benzenediol and 0.016 mol (1.5 g) of magnesium chloride were loaded into the flask. The temperature was increased to 180° C. over 2 hours and then the mixture was aged for 2 hours. After that, the catalyst was removed by an ordinary method and then the remainder was dried at 140° C. under reduced pressure. Thus, X-1 represented by the following general formula (5) was obtained.
