| titleOfInvention | Rectification process of 2, 6-diethylaniline |
| abstract | The invention discloses a rectification process of 2, 6-diethylaniline, which comprises the following steps: s1: preparing raw materials: and (2) carrying out alkylation reaction on aniline, a catalyst and ethylene to obtain a reactant mainly containing 2, 6-diethylaniline, S2: and (3) distillation: and (3) injecting the reactant in the S1 into a distillation device for distillation treatment, and obtaining a crude product of 2, 6-diethylaniline by distillation, wherein the ratio of S3: and (3) filtering: injecting the crude product in the S2 into a large tank for filtering, collecting the filtered 2, 6-diethylaniline material, and recovering the residual waste liquid after filtering, wherein the S4: heating and separating: the filtered 2, 6-diethylaniline feed described in S3 was introduced into the feed pump. The invention reduces the impurity content, improves the quality of the 2, 6-diethylaniline, is convenient for recycling the separated product, avoids the waste of resources and reduces the waste discharge by separating and rectifying the 2, 6-diethylaniline. |
