摘要
在Ｃｕ／Ｚｎ／Ａｌ／Ｚｒ体系催化剂上由异戊醇一步合成异戊酸异戊酯。进料液空速为１．５ｈ￣（－１）、２８５℃、０．６ＭＰａ下转化率５８％，酯选择性９３％；液空速０．５ｈ￣（－１）、２５５℃、０．４ＭＰａ下转化率５４％，酯选择性９８％。反应机理为异戊醇经历脱氢、歧化和酯化三个连续反应进行。
Isopentanoic isopentanoate was synthesized from isopentanol over Cu/Zn/Al/Zr catalyst.The conversion is 58%and the selectivity to isopentanoic isopentanoate is 93%at 285℃,0.6MPa and WHSV=1.5, while the conversion is 54%and the selectivity is 98%at 255℃,0.4MPa,WHSV=0.5.The reaction mechanism is supposed to be consisted of three consecutivereaction steps:dehydrogenation, disproportionation and esterification.
