摘　　要：研究了50℃和46℃时,苯酚和对苯二酚在水中的相行为,它们明显不同于苯酚-对苯二酚在异丙醚中的情形。混合酚类在水中的溶解度大于各个酚单独在水中的溶解度,而酚类与水的两相共存区域则显著被压缩在较小区域,当对苯二酚百分浓度超过3.2%时,混合酚类完全混溶于水中。另一方面,混合酚类在水中完全混溶区域显著扩张,对苯二酚最大质量百分浓度可达25.8%.The phase equilibrium of mixed phenols in water was studied at 46℃ and 50℃ . They are distinctly different from that of diisopropyl ether - Phenol - hydroquinone. The solubility of mixed phenols in water is larger than that of each phenol in water. While two phases co - existing areas of phenols and water are dramatically diminished. Below 3.2 percent for hydroquinone, there are two partially miscible liquids;or it is miscible ccrnpletely. The miscible area of phenols in wa- ter is significantly enlarged. The mlubility of hydroquinone is as great as 25.8 %.
