摘要
以联苯为原料在１５０℃磺化、３４０℃碱熔，制备了４ ，４’二羟基联苯，产率和纯度分别可达８８％ 和９９ ％ 以上。碱熔实验的主次影响因素为：碱用量＞ 反应温度＞ 反应时间＞
dihydroxybiphenyl derived from biphenyl had been prepared by sulfonation at 150℃ and alkali fusion at 340℃.The yield and purity ate 88% and 99% respectively.The turn of primary influencing factors of alkli fusion is :alkli quantity>reaction temperature>reaction time>density of alkli solution.
