摘　　要：简要介绍了苯酚精制过程中含有微量的有机杂质异亚丙基丙酮、羟基丙酮、苯并呋喃的形成机理,及其对苯酚产品质量的影响,并概述了分别使用水滑石型材料(HTM)、ⅥA族金属改性的氧化铝、沸石、酸性离子交换树脂为催化剂的一步苯酚精制法和使用酸性树脂+闪蒸法和两步固体酸法的两步精制法脱除苯酚中羟基丙酮、亚丙基丙酮、苯并呋喃等微量有机杂质的生产技术的新进展。The author briefly introduces the formation mechanism and influence on product quality of trace amounts of mesityl oxide, dihydroxyacetone, and furan and other organic impurities in phenol refining process, and gives an overview on new production technology of one step and two step phenol refining methods of removing phenol hydroxy acetone, sub propyl acetone,benzene and furan trace or- ganic impurities. One step phenol refining method is using HTM, modified alumina, zeolite, acidic ion exchange resin as catalyst to remove organic impurities; two step phenol refining method is using two sections of solid acid and acid resin, and combined with flash method to remove organic impurities.
