合成甲基异丁基酮工艺的技术经济分析

Technology economy analyse of Synthesis of Methyl-isobutyl Ketone (MIBK)

对合成甲基异丁基酮的两种工艺方法及原料路线的技术经济作了详细比较。以异丙醇为原料,常压下不用氢,在非贵金属催化剂上合成甲基异丁基酮(MIBK),较为经济合理。

Comparison of the process for synthesis O MIBK from isopropanol and acetone.Comparison of the technology economy.Selection of synthesis MIBK from isopropanol in one-step process on CuO/Al2O3 catalysts of dehydrogenation, the temperature range of 150-180℃, under atmospheric pressure and space velocity of liquid mixture of 0.5-0.2 (hour) , the conversion of isopropanol is more than 60%, the selectivity of MIBK is higher than 30% , and the life time of such catalysts is longer than 6 months.
