Preparation process of 4,4-dihydroxybiphenyl
摘要:
4,4'-Dihydroxybiphenyl is prepared by decomposing 4,4'-di(2-hydroxy-2-propyl)biphenyl with hydrogen peroxide and an acid catalyst in acetonitrile as a solvent. Especially, this process minimizes the formation of byproducts and permits easy purification of the intended product.
