| 摘要 |
A process is disclosed for converting p-isopropenylphenol and derivatives thereof and, more particularly, oligomers of p-isopropenylphenol and derivatives thereof, to hydroquinone via monomeric intermediates [e.g. p-(2-haloisopropyl)phenol in the case of p-isopropenylphenol and oligomers thereof]. The process involves reacting the starting materials with a hydrogen halide (e.g. gaseous hydrogen chloride) in the presence of an organic solvent and subjecting the product so obtained to oxidation with hydrogen peroxide or an organic hydroperoxide. |
