摘要： Crystals of 6,6'-dihydroxy-3,3,3',3'-tetramethyl -1,1'-spirobiindane (hereinafter referred to as SPI) are obtained by cooling a phenol solution containing 6,6'-dihydroxy-3,3,3',3'-tetramethyl-1,1'-spirobiindane when crystallization is started at a temperature higher than a transition temperature between SPI and an adduct of SPI with phenol. The crystals are washed with an organic solvent or contacted with water and further washed with an organic solvent. When crystallization is started at a temperature less than the transition temperature, adduct crystals of SPI with phenol are obtained from the phenol solution. Phenol is removed from the adduct crystals and the adduct crystals are contacted with water to obtain a hydrate and further the hydrate is washed with an organic solvent.

摘要： A preparation process of high purity bisphenol A from phenol and acetone with a continuous or batch type reactor by on-line estimating with a computer the composition of the reaction mixture and saturated dissolving temperature of bisphenol A under the reaction conditions and by automatically controlling the reaction conditions and liquid transfer conditions of the reaction mixture to the next step. The process does not form crystals of bisphenol A-phenol adduct in the reactor and cooler. A maximum rate of reaction can be obtained. Consequently, fluctuation of reaction temperature can be prevented and the amount of impurities formed is small. The discharge operation of the reaction mixture from the reactor can be carried out steadily and with ease, and does not disturb the operation of successive steps.

摘要： A method for preparing 2,2-bis(4-hydroxyphenyl)propane comprises reacting acetone and phenol in the presence of an acidic ion-exchange resin as a catalyst wherein the reaction of acetone and phenol is performed while removing a part of the water generated during the reaction from a mixed solution containing acetone and phenol by a pervaporation method. According to the method, the water generated through the reaction can rapidly be removed simultaneously with or alternatively to the reaction by a pervaporation operation and, therefore, the catalytic activity of the ion-exchange resin is not impaired at all. Moreover, any complicated operations associated with the dehydration are not required. Thus, the acidic ion-exchange resin catalyst can continuously be used over a long time period without any treatment for the regeneration thereof. Further, according to the method, bisphenol A can be economically prepared from acetone and phenol in a high conversion rate and high yield.

摘要： A phenolic resin composition comprises a mixture of 100 parts by weight of a phenol aralkyl resin and 5 to 60 parts by weight of a novolak type phenolic resin having a content of binuclear components of not more than 10% by area, and a content of trinuclear components of not less than 50% by area and a sum content of tri- and tetra-nuclear components of 75% by area based on the total novolak phenolic resin except for the binuclear components, and an epoxy-cured product obtained by curing an epoxy resin while using the phenolic resin composition as set forth in claim 1 as a curing agent. The phenolic resin composition has a low viscosity and, when it is used as a curing agent for epoxy resins, the resulting epoxy-cured product has a low water absorption rate, is excellent in resistance to moisture and has a high glass transition temperature as compared with the cured product obtained using a novolak type phenolic resin as a curing agent.
