The reaction apparatus used in Example 1 was charged with 4-methylphenol (54 grams), ethylene carbonate (45 grams) and a small amount of KF (0.5 grams, 0.5 percent). After thorough mixing the flask was immersed in an oil bath and the temperature adjusted to 160° C.±2°. After a reaction time of 1.1 hours, CO2 evolution ceased and the product, 4-(2-hydroxyethoxy)methylbenzene (71 grams, 94 percent yield) was recovered and purified by recrystallization from acetone.
