摘要： Product losses and color formation are sometimes encountered in the synthesis of bisphenol A from phenol and acetone in the presence of a cation exchange resin, particularly in the crude product stream from which bisphenol A has been separated via its phenol adduct. Such losses are suppressed and the crude product stream stabilized and decolorized by contact with an anion exchange resin.

摘要： Solvent-based processes for producing latent curing catalysts without causing an extreme exotherm. The process of the present invention includes combining an amine compound curing agent with a solvent, heating the mixture, adding an epoxy/solvent mixture via slow addition, removing the solvent and then heating the remaining composition. Following the heating, a phenolic resin is added to produce the final catalyst. The final catalyst comprises an amine compound, an epoxy, phenolic resin and a solvent. Catalysts having differing properties may be produced by varying the elements of the catalyst.

摘要： In the preparation of bisphenol-A by condensation of phenol with acetone in the presence of an acidic ion-exchange resin catalyst, pretreatment of the catalyst to render it anhydrous comprises two steps to minimize resin degradation. In the first step, from 25 to 90 percent by weight of the resin associated water is removed by vaporization, and in the second step dehydration is completed by saturating the partially dehydrated catalyst with phenol. The advantage of the improvement in the process resides in a more efficient drying, requiring less time and minimal degradation of the resin structure.
