Procedure

A complexation reaction was run as generally described in Example III with a starting mixture of 12.2 g 3,4-xylenol (100 mmole), 0.1 ml absolute ethanol, 5.0 g powdered anhydrous calcium bromide (25 mmole) and some of toluene. After the mixture was stirred for a total of 18 hours it was worked up. A washed-and-dried solid material was obtained in an amount of 10.7 g for a 3,4-xylenol/CaBr2 molar ratio of 1.9:1.0.
