| Abstract: | The promotion effect of strong polar aprotogenic compounds inthe methanol carbonylation to methyl formate catalysed by sodiummethoxide is investigated. The addition of these compounds reduces theapparent activation energy of the reaction, therefore enhances the catalyticactivity of sodium methoxide. It is also found that the addition of thesecompounds can prolong the lifetime of the catalysts even When the inferiorraw materials are used. |
