摘要
以Ｈ型阳离子交换树脂为催化剂，采用三段串联固定床绝热反应器，在酚烯比２．５（ｍｏｌ）、液空速２ｈ－１、反应温度７０～１３０℃条件下使壬烯和苯酚连续烷基化合成壬基酚。在３６０ｈ连续运转期间，壬烯转化率保持在９４％～９５％，而作为对比的两段产物循环绝热反应工艺运行１００ｈ后，壬烯转化率已降至９０％以下。
With H cation resin as catalyst, nonyl phenol is continuously synthesized from nonene and phenolby alkylation in 3-step series adiabatic fixed bed reactors at phenol/nonene ratio of 2. 5 (mol), LHSV2h-' and reaction temprature 70～130 C. Conversion of nonene kept in the range of 94% ￣95 % during360 hours of continuous operation, compared with 2-step adiabatic recycle process whose conversion ofnonene decreased to below 90% after 100 hours of operation.
