| titleOfInvention | A kind of method of preparing aldehyde by hydroformylation of light olefins |
| abstract | A method for preparing aldehyde by hydroformylation of light olefins, belongs to the preparation field of aldehyde.Comprise: (1) provides the first reaction zone and second reaction zone, alkene and synthetic gas contact with the solution containing catalyzer respectively and generate aldehyde in two reaction zones under 60 ~ 120 DEG C with 0.5 ~ 5MPa condition; (2) the first reaction zone product gas phase logistics is sent in second reaction zone; (3) gas stripping column is set between the first reaction zone and second reaction zone, the product liquid phase stream feeding gas stripping column of the first reaction zone and second reaction zone is contacted with synthetic gas, in the product liquid phase stream of reaction zone, unconverted alkene is isolated from liquid phase, and the synthetic gas containing unconverted alkene is returned to reaction zone; (4) product stream after air lift sends into disengaging zone, and be separated with catalyst solution by product aldehyde, the catalyst solution after separation returns to reaction zone.It is simple that the present invention has equipment, avoids and alkene is returned the way that reaction zone need increase supercharging equipment, improves the efficiency of second reaction zone. |
