摘　　要：泰州东联化工有限公司15 kt/a甲基异丁基酮(MIBK)装置采用的是从韩国引进的丙酮一步法生产技术。反应单元使用三相列管式反应器,反应压力为3.0 MPa,反应温度为90～110℃,反应器轴向温差为5～10℃。精馏系统采用7塔工艺流程,由丙酮精馏单元、MIBK精制单元、丙酮回收及二异丁基酮纯化3部分组成。3年多运行结果表明,装置的丙酮单耗[m(丙酮)/m(MIBK)]为1.30～1.35 t/t,产品质量全部达到优级品标准。The methyl isobutyl ketone （MIBK） was produced in a 15 kt/a unit of Taizhou United East Petrochemical Co Ltd by the acetone one -step hydrogenation technology introduced from South Korea. The reaction system was a three - phase tube reactor with pressure 3. 0 MPa, temperature 90- 110 ℃ and axial temperature difference 5 - 10 ℃. The rectification system consisted of 7 columns, such as acetone rectifying unit, MIBK refining unit, acetone recovery and diisobutyl ketone purification unit. The operation results in three years showed that the acetone unit consumption [ m （ acetone ）/m （ MIBK ） ] was 1.30- 1.35 t/t, and the product quality all met the needs of superior grade product standard.
