| titleOfInvention | Method and the device of 2-methyl-2-pentenal serving is extracted in a kind of propionic aldehyde waste liquid |
| abstract | The present invention discloses a kind of method extracting 2-methyl-2-pentenal serving in propionic aldehyde waste liquid, comprises the following steps: (1) is filtered preparing the waste liquid produced in propionic aldehyde process by film unit, and the material its Middle molecule being greater than 2-methyl-2-pentenal serving molecule filters out; (2) mixture after filtration is transported in rectifying tower, heating tower bottom of rectifying tower, makes mixture form azeotropic, isolate gaseous substance by tower top, at the bottom of tower, discharge raffinate; (3) isolated for tower top gaseous substance being condensed into liquid phase is transported in hold-up vessel; (4) detect 2-methyl-2-pentenal serving content in storage pot liquid, underproof conveying is got back in rectifying tower, repeats (2) ~ (3) step; (5) transport of liquid that in step (4), content detection is qualified, in products pot, obtains described 2-methyl-2-pentenal serving.The present invention extracts 2-methyl-2-pentenal serving in the waste liquid preparing propionic aldehyde generation, greatly reduces production cost, can not cause the wasting of resources. |
