| titleOfInvention | Pipelining preparation method of oxodicarboxylic acid diethyl ester analogue |
| abstract | The invention relates to a canalization preparation method of an oxo-dicarboxylic acid diethyl ester analogue, which comprises the following steps: (1) preparing raw materials: dissolving diethyl dicarboxylate serving as a raw material in butyl acetate for later use; (2) preparing a catalyst: dissolving sodium hypochlorite and acetic acid in water for later use; (3) and (3) oxidation reaction: the raw materials and the catalyst firstly pass through a mixer at a certain flow rate and then enter a pipeline reactor for reaction; (4) and (3) post-treatment: and carrying out reduced pressure distillation to obtain a target product. The invention improves the quality of the product, reduces the reaction time, reduces the cost, has simple and safe operation, ensures clean, environment-friendly and efficient production of the product and is more suitable for mass production. |
