在有机综合实验室里和有机化学工业上,时常会碰到接触还原问题。利用接触剂来还原有机物,有许多优点,例如产品纯度高,收获率大,而且所用的还原剂仅仅是价格非常低廉的氢,因此合于工业生产的要求。具有接触还原作用的物质很多,但是作为一个优良的接触剂,必须具备下列各项性能: (一)对氢和被还原物要稳定。(二)能很快的吸着并活化氢分子和被还原物,使其发生预期的反应,并且不发生其他副反 In organic integrated laboratories and organic chemistry industry, often encounter contact reduction problem. The use of contactants to reduce organic compounds has many advantages, such as high product purity and high yield, and the use of reducing agents is only very inexpensive hydrogen, thus meeting the requirements of industrial production. Has the role of contact reduction of many substances, but as an excellent contact agent, must have the following properties: (A) of the hydrogen and the reduction to be stable. (B) can quickly absorb and activate hydrogen molecules and was reduced to make the expected response, and does not occur other Vice
