HY沸石用于苯乙烯与苯酚的烷基化反应,活性好,选择性高。反应温度升高,活性增加,并有利于对位产物的生成;选择合宜的沸石酸量和反应物投料比也对产物生成有利;高温焙烧即可使催化剂再生。
HY zeolite for the alkylation of styrene and phenol, good activity, high selectivity. The reaction temperature increases, the activity increases, and is conducive to the formation of para-products; select the appropriate amount of zeolite acid and reactant feed ratio is also beneficial to the product; calcined at high temperatures can make the catalyst regeneration.
