摘要
对叔辛基酚(PTOP)作为二异丁烯(DIB)的下游产品,是一种用途广泛、具有广阔的市场前景的精细化工产品。通过优化工艺条件,利用国产阳离子交换树脂C102-2/9826,在苯酚(PhOH)与DIB摩尔比为3:1,催化剂加入量0.42%(重量比),反应温度80℃条件下,接触2小时DIB转化率达到98.79%以上,产物中PTOP选择性可达89.39%,蒸馏后产品纯度大于 98.00%。
P - tert - octylphenol (shorten by PTOP), the alkylation product of phenol with diisobutylene(shorten by DIB), has been largely applying in varied fields such as rubbers, oil additives and so on. By improving alkylation conditions, a satisfactory result has been achieved, that is, selectivity of PTOP is above 89% when conversion rate of DIB is 99% with the ion exchange resin catalysts made in our own country.
