| titleOfInvention | The device that a kind of propionic aldehyde is purified |
| abstract | The utility model discloses the device that a kind of propionic aldehyde is purified, it is characterized in that: comprise compression rectification tower, recirculation control device and overhead condenser, described compression rectification tower entrance is connected with thick propionic aldehyde access port, described compression rectification column overhead is provided with vapour outlet, at the bottom of tower, be provided with discharge outlet, described discharge outlet is connected with products pot by delivery tube; Described vapour outlet is connected with overhead condenser import by delivery tube, and described overhead condenser outlet is connected with described reflux import by delivery tube, and described reflux outlet is connected by delivery tube with residual liquid tank, rectifying tower respectively.The utility model is that propionic aldehyde and water are formed to azeotropic in rectifying tower, and moisture is progressively evaporated, and leaves the propionic aldehyde that purity is higher, and circulation rectifying finally can obtain purity up to 99.9% propionic aldehyde. |
