What is molecular sieve 3A?
BASF 3A Molecular Sieve is a synthetic crystalline aluminosilicate with a regular micropore structure. BASF 3A Molecular Sieve is commonly used for drying of gases and polar liquids (methanol, ethanol) and easily polymerizable substances, such as unsaturated hydrocarbons (ethylene, propylene, acetylene and butadiene).
How do you use 3A molecular sieves?
Place the container of hot, regenerated sieves on the porcelain plate of a glass desicator and place under vacuum while they cool. Put dry sieves into bottles with polyethelene cap liners to keep dry until needed. Type 3A molecular sieves will reduce water in an air stream to 0.001 mg/liter air.
How do you regenerate 3A molecular sieves?
To regenerate the sieve you need to remove the adsorbed moisture and other materials. To regenerate 3A Molecular Sieve heat to 250ƒ. Keep 3A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.
What are 4A molecular sieves?
4A molecular sieve means the molecules with the pore size of 4A0 or 4 angstroms are used for the adsorbing process. It simply signifies that molecules with the pores size larger than 4a cannot be used for adsorption. Generally, they are the sodium forms of the Type A structure.
How do you dry DCM with molecular sieves?
The distilled product should be stored in an amber-colored bottle away from bright light with Linde type 4A molecular sieves in an atmosphere of dry nitrogen. Add about 50 g of 4 Å molecular sieve, (more if your solvent is really wet) per liter of solvent and wait for a week.
What is 4A Zeolite?
Doucil®4A zeolite. DOUCIL® 4A is a zeolite of the first generation optimized for use as a builder, liquid carrier and/or processing aid in laundry detergent products, helping manufacturers to produce detergents with excellent physical properties and cleaning performance.
What is Molecular Sieve 13X?
BASF 13X Molecular Sieve is a highly selective adsorbent designed for the elimination of trace contaminants from air and other gases. It can also be used for the desulphurization (sweetening) of natural gas and other fluids, especially for the removal of mercaptanes, and for drying of gases and liquids.
Molecular Sieve 3A is an alkali metal aluminosilicate; Molecular sieve 3A is the potassium form of the type A crystal structure. Molecular sieve 3A adsorbs molecules with effective diameters small than 3 anstrom (0.3nm) such as water and exclude molecular
What is the weight of a molecular sieve?
Drums: 150 kg / 330 lb. Super Sacks: Fill weight to order specification. Molecular sieve is also know as a zeolite. A zeolite is a conformation of hydrated aluminosilicates of sodium, potassium, calcium, or other cations.
How do I prevent moisture adsorption on 3A molecular sieve?
Keep 3A molecular sieve in an air tight container until ready for use to avoid unintended moisture adsorption. Molecular sieve 3A can be regenerated or activated either thermal regeneration method (Thermal Swing Adsorption, TSA); To remove moisture from a 3A molecular sieve, a temperature of 200-230°C (390-570°F)is required.
What is zeolite molecular sieve 3A?
Zeolite molecular sieve 3A is used for drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene) 2. Zeolite molecular sieve 3A is used in deep desiccation of cracked petroleum gases, such as ethylene, propylene, butadiene, acetylene and natural gas, and of polar liquid, such as ethanol, LPG and solvent
