Abstract

The invention provides a production method of alkoxy phenol adsorption resin. Divinylbenzene is adopted as a main crosslinking agent, and 1,4-bis(ethylene phenoxy)butane and dially phthalate serve as assistant crosslinking agents, thus the adsorption property of the resin on alkoxy phenols is improved.

Description

technical field [0001] The invention relates to a preparation method of resin, in particular to a production method of alkoxyphenol adsorption resin. Background technique [0002] Resin adsorption method is used to produce phenol wastewater, gas production wastewater, coking wastewater, dicumyl peroxide (DCP) production wastewater, bisphenol A production wastewater, salicylic acid production wastewater, p-nitrophenol ( Sodium) production wastewater, p-nitrophenyl ethyl (methyl) ether production wastewater, phenolic resin production wastewater, pentachlorophenate sodium production wastewater, T-50 petroleum ester production wastewater, 2-methyl-4-chlorophenoxyacetic acid production The treatment of phenol-containing wastewater, p-aminophenol production wastewater and other phenol-containing wastewater has been successful. However, the treatment effect of wastewater containing alkoxyphenol is not high. [0003] CN4607158A provides a kind of phenolic hydroxyl modified adsorpt...
