摘要: <正> 引言 双酚A是生产聚碳酸酯、环氧树脂的关键原料.双酚A-苯酚加合物晶体是双酚A生产过程中的重要中间产物,该加合物晶体是由双酚A和苯酚形成的等摩尔比的结晶化合物,其结构式如下:

Abstract: The data of equilibrium decomposition pressure of bisphenol A - phenol adduct and saturated vapore pressure of bisphenol A and phenol solution were measured. Comparing the curves of the saturated vapor pressure of phenol and bisphenol A - phenol solution with the equilibrium decomposition pressure of bisphenol A-phenol adduct , it was found that the latter is higher than the former two. This discovery provided the experimental basis for direct dephenolization from the crystal adduct of bisphenol A-phenol using the solid decomposition reaction principle to obtain the bisphenol A whith high quality.
