Abstract

The invention relates to a preparation method of an adsorbent for refining trimesic acid. Triallyl cyanurate, p-fluorocinnamaldehyde, 1-allyl-3-methylimidazolium tetrafluoroborate and 4-hydroxynonenal are introduced in styrene cross-linking polymerization to serve as comonomers to prepare the adsorbent.

Description

technical field [0001] The invention relates to a preparation method of an adsorbent, in particular to a preparation method for refining a trimesic acid adsorbent. Background technique [0002] Trimellitic acid (1,3,5-benzenetricarboxylic acid) is an important chemical raw material, which is of great significance to the production of plastics, artificial fibers, water-soluble alkyl resins, plasticizers, etc., and is used to manufacture polymer separation High-tech new fields such as membranes and pharmaceutical intermediates are also used in the separation and purification of rare earth metal ions, anticancer drugs, plant growth regulators, fungicides, preservatives, and gas chromatography column fixation. They are mainly used to prepare solids in rocket propulsion Fuel cross-linking agent, aldol resin, water-soluble baking varnish, high-performance plastic plasticizer and reverse osmosis membrane material for seawater desalination, etc. [0003] CN104513156A relates to a m...
