| titleOfInvention | Method for catalytically recovering phenol in anisole synthesis process by methanol method |
| abstract | The invention discloses a method for synthesizing phenol in an anisole process by a methanol catalytic recovery method, which comprises the steps of reacting phenol and methanol in a gas phase to synthesize the phenol recovered in the anisole process and 2, 6-dimethyl anisole in a mixture of the phenol and the 2, 6-dimethyl anisole by a catalytic conversion method to generate 2, 6-dimethyl phenol and methanol under the action of a catalyst, and then realizing effective separation of the phenol and the 2, 6-dimethyl anisole by a conventional rectification process, thereby overcoming the problem that the 2, 6-dimethyl anisole and the phenol cannot be separated by adopting a rectification tower due to the fact that the boiling points are close to each other. The catalyst used in the method has the advantages of simple preparation process, low cost, high conversion rate for catalyzing the reaction of 2, 6-dimethyl anisole, good selectivity and long service life, and can realize the purpose of simply and rapidly separating phenol and 2, 6-dimethyl anisole, simultaneously the generated 2, 6-dimethyl phenol can be sold as a product, and the separated phenol and methanol can be continuously recycled as raw materials for synthesizing anisole. |
