Catalyst for liquid phase synthesis of methyl isobutyl ketone through acetone hydrogenation and applications thereof

The invention discloses a catalyst for liquid phase synthesis of methyl isobutyl ketone (MIBK) through acetone hydrogenation and applications thereof. The catalyst comprises three effective components namely fluorine modified magnesium oxide, titanium dioxide, and palladium and other auxiliary components. The catalyst is applied to high pressure liquid phase reactions of acetone hydrogenation to prepare methyl isobutyl ketone; the acetone conversion rate can reach 70.7%, MIBK selectivity can reach 78.6%, and corresponding MIBK yield can reach 55.6%. In a kettle type reactor, the MIBK yield is 45.6 mol MIBK/g Pd for one unit mass of palladium (primary reactions). Compared with similar catalysts, the catalyst has the characteristics of high MIBK yield, little using amount of palladium, and simple preparation technology. 种丙酮加氢液相法合成甲基异丁基酮的催化剂及应用。该催化剂包含氟改性氧化镁、二氧化钛、钯三种有效组份及其他辅助成份。本发明催化剂用于丙酮加氢合成甲基异丁基酮的高压液相反应中，丙酮转化率可达70.7％，MIBK选择性可达78.6％，相应的MIBK收率达55.6％。釜式反应器中次反应单位质量钯的MIBK收率达45.6mol/g。与同类催化剂相比，该催化剂具有MIBK收率高、钯用量少、制备工艺
