摘要： High quality bisphenol A is produced from a neutral crystalline adduct of bisphenol A and phenol by fusing the adduct in an atmosphere having a maximum oxygen content of 0.005 % by volume, followed by evaporation of liberated phenol. The crystalline adduct may be mixed with an aliphatic carboxylic acid before the fusion to reduce the coloring of the product. When an acidic crystalline adduct is used, the use of a strong alkali salt of an aliphatic carboxylic acid is suitably used. Interior surfaces of the apparatuses for carrying out the fusion and evaporation are desirably washed with an organic solvent to remove oxygen therefrom. The evaporation of phenol is suitably performed by two stage steam stripping wherein a used stripping gas obtained in the second stage is employed as a stripping gas in the first stage while steam is used as the stripping gas in the second stage.
摘要翻译：通过在最大氧含量为0.005体积％的气氛中将加合物熔合，然后蒸发游离的苯酚，由双酚A和苯酚的中性结晶加合物制备高品质双酚A。结晶加合物可以在融合之前与脂族羧酸混合以减少产物的着色。当使用酸性结晶加合物时，优选使用强力的脂族羧酸的碱金属盐。用于进行熔化和蒸发的装置的内表面理想地用有机溶剂洗涤以从其中除去氧。苯酚的蒸发适宜地通过两步蒸汽汽提进行，其中在第二阶段使用在第一阶段中获得的用过的汽提气体作为第一阶段的汽提气体，同时在第二阶段使用蒸汽作为汽提气体。

摘要： A crystalline adduct of bisphenol A and phenol is produced by crystallization of a phenolic slurry of bisphenol A. The crystallization of the slurry is performed by continuously discharging a portion of the slurry from the crystallization zone into a plurality of cooling zones and then recycling the cooled slurry to the crystallization zone. The cooling zones are connected in parallel and they are operated so that at any one time one of the cooling zones can be cleaned of deposits of crystalline adduct without stopping the process.
An apparatus having a plurality of coolers and suitable for effecting the above crystallization process is also disclosed.

摘要： A gaseous mixture of steam, phenol and bisphenol A, such as is obtained in the manufacture of bisphenol A, is treated for recovery of bisphenol A and phenol by the steps of:

(a) introducing the gaseous mixture into a first cooling zone maintained at a pressure of 30 Torr or less and such a temperature that the steam is prevented from condensing while a portion of the phenol is condensed, wherein the gas is brought into counter-current contact with a first liquid cooling medium to condense substantially all of the bisphenol A and part of the phenol and thereby obtain a mixed gas containing uncondensed steam and uncondensed phenol, the first liquid cooling medium being phenol or bisphenol A-containing phenol; and
introducing the mixed gas into a second cooling zone maintained at a pressure of 30 Torr or less and such a temperature that substantially all of the mixed gas is condensed, wherein the gas is brought into counter-current contact with a second liquid cooling medium to condense substantially all of the mixed gas and thereby obtain a condensate-containing liquid, the second liquid cooling medium being an aqueous solution of phenol.

摘要： High purity, crystalline adduct of bisphenol A and phenol is produced multi-stage crystallization of a phenolic slurry of bisphenol A with a crystal separation and washing step being interposed between each of the two stages. Each of the crystallization stage includes a series of crystallization towers operated at decreasing temperatures. The crystallization of the slurry is performed by continuously discharging a portion of the slurry from each of the crystallization towers, introducing the discharged slurry into one or more coolers and then recycling the cooled slurry to the tower. Another portion of the slurry in each crystallization slurry is continuously discharged, heated for dissolving fine crystals of the adduct and then recycled to the crystallization tower so that large crystals are grown in each of the crystallization steps. An apparatus having a plurality of coolers and suitable for effecting the above crystallization is also disclosed.
