Title:
METHOD FOR PRODUCING MIXED ETHER FROM MIXED PHENOL AND METHOL BY GAS PHASE ETHERIFICATION
Document Type and Number:
WIPO Patent Application WO/2019/119363
Kind Code:
A1
Abstract:
Disclosed is a method for producing a mixed ether from a mixed phenol and methol by gas phase etherification, at least comprising the following steps: a mixture containing the mixed phenol and methol is passed through a reaction zone containing an etherification catalyst for reaction, so as to obtain the ether. The method for producing a mixed ether from a mixed phenol and methol uses the mixed phenol and methol as raw materials, has a selectivity for an etherification product which can reach 98% or more, and the catalyst has a good stability; and the production process has no equipment corrosion, with the catalyst being environmentally friendly, and has good industrial application prospects.
