English name: Molecular sieves type 5A; Calcium Sodium Alumino-Silicate
Other names: 5A molecular sieve; calcium-A molecular sieve
CAS number: 69912-79-4
Molecular formula: CanNa12-2n [(AlO2) 12 (SiO2) 12] · xH2O
Level: CP
Bulk density: 0.69 ～ 0.75 g / mL
Compressive strength / N: ≥65.0
Moisture: ≤1.5%
Water adsorption capacity (10% RH): ≥20.0%
Traits: white strips. The pore size of 5A molecular sieve is about 5 angstroms. It is generally called calcium molecular sieve. In addition to the effects of 3A and 4A molecular sieves, it can also adsorb C3-C4 normal paraffins, ethyl chloride, ethyl bromide, butanol, etc. It can be widely used in oxygen and nitrogen production industries, and at the same time absorb moisture, carbon dioxide and some organic gases. After adding the adhesive, it can be shaped into strips or balls. A microporous adsorbent of polyhydrated aluminosilicate, synthetic zeolite. Hygroscopic. Soluble in strong acid or alkali and decompose, insoluble in water and organic solvents. There are irritating uses: biochemical research. Selective adsorbent. Catalyst or catalyst carrier. For the separation of normal and isoparaffins and the separation of oxygen and nitrogen, the desulfurization of petroleum and petroleum gas, the drying and purification of gases and liquids: RT
