| titleOfInvention | Process method for producing high-purity isobutene and ethylene glycol mono-tert-butyl ether |
| abstract | The invention discloses a production process for simultaneously producing high-purity isobutene and ethylene glycol tert-butyl ether, belonging to the field of chemical product process production. The production process comprises the steps of generating a crude product of ethylene glycol mono-tert-butyl ether by ethylene glycol and isobutene in mixed C4 under the action of a solid catalyst, and preparing an ethylene glycol mono-tert-butyl ether product by rectifying and purifying part of the crude product of the ethylene glycol mono-tert-butyl ether; the rest part of crude ethylene glycol mono-tert-butyl ether is subjected to cracking reaction under the action of a solid catalyst to generate a high-purity isobutene product. Compared with the traditional process for preparing high-purity isobutene, the process has the advantages of simple process flow, small equipment investment, easy product separation, low energy consumption, good product quality and the like; meanwhile, the novel environment-friendly solvent ethylene glycol mono-tert-butyl ether can be produced, the market risk resistance of the device is improved, and the total production cost is reduced; is an advanced process method. |
