摘要：

Homogeneous synthesis of methanol from synthetic gas was carried out in the Ni(CO)(4)/KOMe catalytic system. The influence of various factors, such as the reaction temperature, the concentration of potassium methoxide, the concentration of nickel tetracarbonyl and the reaction pressure on the catalytic activity, was discussed, respectively, and the most preferred conditions were obtained. The results showed that methanol could be prepared from carbon monoxide and hydrogen under mild reaction conditions. The catalytic reactions were operated most preferably at 378 K and 1.8 MPa. The activity of catalyst characterized by space-time yield (STY) is about 4 mol/1 h. The effect of additives containing N-, O-, S-elements on the catalytic activity was also investigated.
