The present invention relates to the preparation of phenol from chloro-benzene. In the preparation of phenol the methods in current commercial use are those wherein either the alkali metal salts of benzene sulfonic acid are fused with an alkali metal hydroxide, or chlorobenzene is hydrolized......
(57) using a catalyst such as ZSM-11 zeolite or [Abstract] ZSM-5, parts by nitrous oxide molar less than aromatic compounds such as benzene, phenol, chlorobenzene, fluorobenzene, toluene, such as ethylbenzene how to oxidation. The method is advantageous for the production of phenol from benzen...
摘要: A process for producing m-phenoxybenzyl alcohol by reacting chlorobenzene with m-hydroxybenzyl alcohol in the presence of a copper catalyst and a base, the process being characterized by using an alkylene glycol as a reaction solvent.
