HZSM─5（55）对乙酸和异戊醇酯化反应催化活性的研究

STUDY ON CATALYTIC PREPERTY OF HZSM-5(55)ZEOLITE FOR THE ESTERFCATION REACTION OF ACETIC ACID AND LSOAMYL ALCOHOL

以ＨＺＳＭ—５（５５）原粉为原料改性．６００℃焙烧的催化剂，对已酸异戊醇酯化反应有较好的催化活性和稳定性。其最佳反应条件为：温度：１３５～１４０℃；酸醇比：３；原料空速：２—３ｈ１－１．

The very good activity and stability Catalyst was studied. When HZSM-5(55)was modified and talcinatiedat 600℃. It was used catalyst for esterification of acetic acid and isoamyl alcohol.The best reaction conditions ;temperature is 135-140℃,molretio of acid to alcohol is 3 and the rate of feed is 2-3h-1.
