Abstract
PURPOSE: To prepare the title compound, useful as an intermediate of agricultural chemicals and perfumes, in high yield, by the dehydrating condensation of monohydric phenols and dihydric phenols in the presence of an organic sulfonic acid.
CONSTITUTION: Hydroxydiphenyl ethers of formula III (e.g. p-hydroxydiphenyl ether) are obtained by the dehydrating condensation of monohydric phenols of formula I (R is lower alkyl or halogen; n is 1, 2) (e.g. phenol) and dihydric phenols of formula II (e.g. hydroquinone) in the presence of an organic sulfonic acid (e.g. p-toluenesulfonic acid). The amount of the catalyst used is preferably 0.5W30wt% of the total amount of the starting materials, i.e. the monohydric phenols and the dihydric phenols.
