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： 2,6-DI-TERT.-BUTYL-4-CUMYL PHENOL IS PRODUCED BY REACTING P-CUMYL PHENOL WITH ISOBUTYLENE, AT A REACTION TEMPERATURE OF FROM 40.degree. TO 120.degree.C. in the presence of from 0.01 to 20% by weight of p-toluene sulfonic acid based on the weight of the p-cumyl phenol. Isobutylene is charged into the reaction system at a high rate and is always present in the reaction system during the reaction. A substantially 100% conversion of p-cumyl phenol is attained and the weight ratio of 2,6-di-tert.-butyl-4-cumyl phenol/2-tert.-butyl-4-cumyl phenol in the reaction product is greater than 10, while splitting off of the cumyl group at the para position is suppressed.
