Description

technical field

[0001] The invention relates to a method for producing cyclohexenyl cyclohexanone, an intermediate of o-phenylphenol, in particular to a method for producing cyclohexenyl cyclohexanone through continuous condensation using cyclohexanone as a raw material. Background technique

[0002] O-phenylphenol (OPP) is a fine chemical and organic intermediate with a wide range of uses. It can be used as antiseptic, antifungal agent, broad-spectrum fungicide, used for fruit preservation, cosmetics, wood preservation, and household, public places, Disinfection of swimming pools and hospitals, it can also be used to produce oil-soluble o-phenylphenol formaldehyde resins, non-ionic emulsifiers, synthetic dyes, water-based cutting fluids, etc. Agents and intermediates of flame retardant polymer materials, etc. At present, cyclohexanone is mainly used as raw material at home and abroad, and the intermediate - cyclohexenyl cyclohexanone is obtained through condensation and de...
