Abstract

Disclosed is a synthesis method of nonylphenol ethoxylate polyoxypropylene ether, belonging to the compound synthesis technology field, which uses nonylphenol, propylene oxide and ethylene oxide as materials, performing polymerization by first adding propylene oxide or ethylene oxide in the presence of a catalyst, and performing polymerization by secondly adding ethylene oxide or propylene oxide to prepare nonylphenol ethoxylate polyoxypropylene ether; wherein, the catalyst is a mixture of one or more of solid sodium methoxide, sodium methoxide methanol sollution, KOH, NaOH, etc., the amount of the added catalyst is 0.1-1.0% by weight of prepared nonylphenol ethoxylate polyoxypropylene ether. The invention uses two steps of polymerization, the reaction condition is gentle and is easy to control, the request on the device is low, the prepared products has wide preparation range for emulsifier or demulsifier and is easy to control.

Description

technical field [0001] The invention relates to a method for synthesizing nonylphenol polyoxyethylene polyoxypropylene ether, which belongs to the technical field of organic compound synthesis. Background technique [0002] Some of the existing nonylphenol ethers are block polyethers with ethylene oxide added and no propylene oxide or ethylene oxide added. The range of the product can be adjusted is small, which affects the performance of the product. Contents of the invention [0003] The purpose of the present invention is to provide a method for synthesizing nonylphenol polyoxyethylene polyoxypropylene ether with reasonable technology, simple operation and good usability. [0004] The present invention is the synthetic method of nonylphenol polyoxyethylene polyoxypropylene ether, with nonylphenol, propylene oxide (PO), ethylene oxide (EO) as raw material, it is characterized in that under the existence of catalyst, add ring Propylene oxide or ethylene oxide is polymeri...
