Procedure
In 500 ml of acetonitrile were dissolved 168 g of 1-p-methoxyphenoxy-2-propanol and 62 g of p-methoxyphenol. To the solution was added 50 g of a 48% sodium hydroxide aqueous solution, and the mixture was allowed to react at 80° C for 3 hours while stirring. The reaction mixture was poured into water, and the precipitated crystals were collected by filtration and recrystallized from methanol to obtain 110 g of 1,2-bis(4-methoxyphenoxy)propane having a melting point of 84 to 84.5° C.
