Process for producing aldehyde |
摘要 |
A process for producing an aldehyde, which comprises a reaction step of producing an aldehyde by reacting an olefinic compound with carbon monoxide and hydrogen in the presence of a rhodium complex catalyst comprising at least rhodium and an organic phosphite in a reaction zone, a separation step of obtaining a catalyst solution containing the rhodium complex catalyst by separating the aldehyde from a reaction solution taken from the reaction zone, and a recycling step of recycling the catalyst solution into the reaction zone, wherein the aldehyde is separated from the reaction solution in such a manner as to make an aldehyde concentration from 0.5 to 99 wt % in the catalyst solution. |
