DOWEX(R) 50X4-400 - Uses and synthesis methods
introduction
Ion exchange resins can be divided into strong basic anion exchange resins and weak basic anion exchange resins according to the properties of exchange groups. Anion exchange resin has high strength, superior performance and wide range of uses, and can be used in biochemical separation, sewage treatment, phase transfer catalytic reagents and other fields. Ion exchange resin is a kind of network polymer material with functional exchange groups, generally in the form of 0.04~1.2mm colloidal particles. The particle size and its distribution of ion exchange resin are one of the basic factors affecting the properties of the resin. Poor particle size uniformity will not only cause a large amount of resin loss, but also cause problems such as blockage of resin beds or pipes. The prior art is generally controlled by changing the size of polymer droplets during suspension polymerization.

application
It is mainly used for drying natural gas, various chemical gases and liquids, refrigerants, medicines, electronic materials and variable substances, argon purification, and separation of methane, ethane and propane.
storage condition
room temperature; The relative humidity is not more than 90%; It is not suitable to be directly exposed to the air; Avoid water, acid and alkali.
use
It is mainly used for adsorption and separation of aromatic hydrocarbons and paraffin purification. 10X molecular sieve can adsorb isoparaffins, aromatics and naphthenes with diameters less than 9A. When used for refining crude liquid paraffin, polar compounds such as nitrides, organic acids, sulfides and aromatics in crude paraffin can be preferentially adsorbed and separated. So that the polar compounds mentioned above are separated from the crude liquid.
production method
hydrothermal synthesis method uses water glass, sodium metaaluminate and sodium hydroxide as raw materials. For the preparation of water glass solution and the preparation of sodium metaaluminate, please refer to 3A molecular sieve.
Mix sodium silicate, sodium metaaluminate, and sodium hydroxide according to a certain molar ratio (generally A12O3:SiO2:Na2O:H2O = 1:2:3:185), and react at a temperature above 40 ℃ with strong stirring to form Gel, then heat up to (102±2)℃, and crystallize statically at this temperature to form crystalline powder, and then filter, wash, and dry to obtain 4A molecular sieve powder, it is kneaded with the adhesive, formed, and burned and activated at a certain temperature to prepare 4A molecular sieve.
