Dowex 50W-X4

beads

The hydrothermal synthesis method uses water glass, sodium metaaluminate and sodium hydroxide as raw materials. See 3A molecular sieve for the preparation of water glass solution and the preparation of sodium metaaluminate. Mix water glass, sodium metaaluminate and sodium hydroxide according to a certain molar ratio (usually A12O3: SiO2: Na2O: H2O = 1: 2: 3: 185), react at 40 ℃ or more with vigorous stirring to form a gel , And then raise the temperature to (102±2) ℃, and statically crystallize at this temperature to form a crystalline powder, and then filter, wash, and dry to obtain 4A molecular sieve powder, which is kneaded with a binder, shaped, and at a certain temperature 4A molecular sieve was prepared by burning activation.

DOWEX(R) 50WX4 HYDROGEN can be used for chromatographic analysis. Used for the separation of methane, ethane and propane. Can also be used as desiccant and detergent components.
DOWEX(R) 50WX4 HYDROGEN is mainly used for adsorption separation of aromatic hydrocarbons and refining of paraffin. 10X molecular sieve can adsorb isoparaffins, aromatic hydrocarbons and naphthenes with diameter less than 9A. When used in the purification of crude liquid paraffin, it can preferentially select and separate the polar compounds such as nitrides, organic acids, sulfides and aromatic hydrocarbons in the crude paraffin. Thus, the above polar compounds are separated from the crude liquid.
