摘要
通过对无灰分散剂烃化工艺的改进工业应用研究表明 ,降低烃化反应过程的通氯温度和速率 ,降低烃化反应温度和气提温度以及缩短烃化反应时间和气提时间可使烃化反应产物聚异丁烯基丁二酸酐质量合格 。
WT5BZ]Industrial testing results of the improved PIBSA process for producing ashless dispersant show that the quality,nitrogen content and appearance of the finished product can be improved by reducing the rate of feeding and temperature of chlorine,and reducing the temperature and time of the reaction and nitrogen extraction [WT5HZ][
