Procedure

To a reaction flask containing 500 ml of methylene chloride under a nitrogen atmosphere is added with stirring phosphorus pentoxide (270 g, 1.9 moles). 2-Butoxyethanol (425 g, 3.6 moles) is added from a dropping funnel over about 2 hr, during which a gentle reflux occurs. At the end of the addition, only a small amount of unreacted P2O5 remains. The contents of the flask are a clear yellow solution. At the end of 24 h additional reaction, the contents of the flask are darker in color and no P2O5 is observed.
