Abstract

The invention provides a preparation method of carbon tetrachloride purification adsorbent. The preparation method comprises the steps of adding water and polyvinyl alcohol into a reaction kettle and evenly mixing to form a water phase; adding styrene, 1,5,9-cyclododecatriene, 3-allyloxy-2-hydroxy propane sulfonic acid, methacrylamide and pentamethyl cyclopentadienyl isopropyl titanate into a reaction kettle and evenly mixing to form an oil phase; adding an oil-phase solution into the reaction kettle where the water phase is prepared; reacting in an appropriate temperature; acetone extracting reaction mixture after reaction is finished; drying in a vacuum mode to obtain the carbon tetrachloride purification adsorbent. The carbon tetrachloride purification adsorbent is large in specific surface area, stable in property and high in product purity after adsorption.

Description

technical field [0001] The invention relates to a preparation method of an adsorbent for purification, in particular to a preparation method of an adsorbent for carbon tetrachloride purification. Background technique [0002] Carbon tetrachloride is a colorless and toxic liquid that can dissolve various substances such as fat and paint. It is a volatile liquid with a slightly sweet smell of chloroform. Carbon tetrachloride is immiscible with water and miscible with ethanol, ether, chloroform and petroleum ether. It is an organic solvent with excellent properties, and is also used for chlorination of organic substances. It is widely used in the extraction of drugs, pharmaceuticals, textiles, food, and industrial production. High-purity carbon tetrachloride is more conducive to the production of related products and the quality of the products produced. [0003] CN2573497 discloses an adsorption column for carbon tetrachloride purification. It comprises an adsorption column...
