| 英文摘要 | A system and method for producing polyoxymethylene dimethyl ethers (DMMn) using an aqueous formaldehyde solution as the initial reaction material. The process system has a polymerization reaction unit, an acetalation unit, a product separation unit, and a catalyst regeneration unit. Both polymerization and acetalation reaction are conducted in the presence of an ionic liquid as a catalyst, which can achieve the effect that two different reactions may be catalyzed by the same ionic liquid. The present invention employs a simple catalyst system, and achieves the efficient separation of the catalyst, the byproduct water, the product and the reaction materials in a separation manner combining the extraction and the rectification. |
