Molecular sieves, 4A, 1-2mm (0.04-0.08in) dia. pellets


Chemical Properties

Storage & Sensitivity
Hygroscopic. Ambient temperatures.
Insoluble in cold water, hot water, methanol, diethyl ether, n-octanol and acetone.


Molecular sieves, 4 Å is used to absorb molecules as large as butane. It is utilized for the separation of natural gas, liquified petroleum gas (LPG) and alkenes. It finds application in the refining and purification of liquid and gases. It is also used for drying and purification of air, inert gases and solvents. It is actively involved to remove methanol, carbon dioxide and ammonia from fluid streams. It plays a vital role to remove heavy metal ions available in water. It is also used as a soap forming agent and as a detergent auxiliary. It has been considered as a general-purpose drying agent in polar and non polar media.


Hygroscopic. Incompatible with hydrogen fluoride, strong acids, strong bases and strong oxidizing agents.
