Abstract: This invention relates to the purification of phenol produced by the decomposition of cumene hydroperoxide by heating the phenol with a polyamine compound to remove carbonyl-bearing impurities and then acidifying the phenol to give a product which remains color stable on aging. After the addition of the polyamine compound, the phenol is distilled free of the polyamine compound and the carbonyl-bearing impurities. This distillation can be carried out either before or after the acid is added.

Abstract translation: 本发明涉及通过用多胺化合物加热苯酚以除去含羰基杂质，然后酸化酚，得到在老化时保持颜色稳定的产物，通过氢过氧化枯烯的分解而产生的苯酚的纯化。 加入多胺化合物后，不含多胺化合物和含羰基杂质蒸馏出苯酚。 该蒸馏可以在酸加入之前或之后进行。

Abstract: ALPHA ETHY STYRENE, OBTAINED AS A BY-PRODUCT IN THE MANUFACTURE OF PHENOL ISHYDROGENTED BACK TO CUMENE USING HYDROGEN AND STANDARD HYDROGENATION CATALYSTS WHICH ARE SELECTIVE FOR THE ETHYLENIC SIDE CHAIN. PRIOR TO HYDROGENATION THE ALPHA METHYL STYRENE IS TREATED TO EFFECT REMOVAL OF HYDROXY ACETONE PRESENT. BY REDUCING OR ELIMINATING HYDROXY ACETONE, POISONING OF THE CATALYST SI PREVENTED. HYDROXY ACETONE IS REMOVED FROM THE ALPHA METHYL STYRENE BY WATER WASHING, DISTILLATION, OR BY CHEMICAL METHODS AS FOR EXAMPLE BY TREATING WITH AN AMINE.
