| titleOfInvention | Device for removing excessive organic amine in process of synthesizing alkyl ketene dimer |
| abstract | The utility model relates to an alkyl ketene dimer production field specifically provides a remove device of excessive organic amine in synthetic alkyl ketene dimer technology. The device for removing the excessive organic amine in the process of synthesizing the alkyl ketene dimer sequentially comprises a normal-pressure evaporation device and a reduced-pressure evaporation device; the normal pressure evaporation device and the reduced pressure evaporation device both comprise a centrifugal unit for centrifuging the material to make the material attached to the inner wall of the centrifugal unit; the normal-pressure evaporation device and the reduced-pressure evaporation device comprise rollers, and the rollers are positioned in the centrifugal unit and are used for rolling materials on the inner wall of the device into uniform films. The method solves the problems that in the prior art, in order to eliminate organic amine in AKD synthesis, acid water is generally adopted for removal, but in the process of removing the organic amine by adopting the acid water, a large amount of acid water is needed, resource waste is caused, and the organic amine and the acid water generate salts which are difficult to recycle. |
