摘要:用各种贱金属负载的催化剂将乳酸甲酯(ml)加氢脱氧(hdo)变成丙酸甲酯(mp).在220oc和50 Bar H 2的条件下,在甲醇中使用双金属fe-ni / Zro 2可获得77%的高收率.使用的fe-Ni /的zro在ni的协同效果提高mp的收率显著2代替的fe /的zro 2单独.此外,Zro 2载体有助于提高产率,因为金属掺杂后zro 2从四方晶向单斜晶发生了相变,从而导致fe和ni在zro 2上的精细分散,从而提高了材料的催化活性. .有趣的是,观测到fe-Ni / Zro2还有效催化甲醇重整以原位产生h 2,然后进行ml的hdo,在220oc下用50 Bar N 2代替h 2产生60%mp .fe-ni / Zro 2还可将其他短链烷基乳酸酯的hdo催化为相应的丙酸烷基酯,产率约为70%.fe-Ni / Zro 2的活性在连续五个反应运行中均未发生损失,这表明催化剂体系具有很高的耐久性.

摘要:A catalyst for producing an aryl ester of a carbonic or carboxylic acid is disclosed, which includes a microporous material containing a metal element belonging to group IV. This catalyst can be used as a heterogeneous catalyst to produce the aryl ester in high yield with industrial advantages. In order to produce the aryl ester using the catalyst, a carbonate or an aliphatic carboxylate is transesterified with an aromatic hydroxy compound, or an aryl carboxylate is transesterified with a carbonate, or an alkyl aryl carbonate is disproportionated by transesterification.
