MDL
MFCD00147627

Propriétés chimiques

Sensibilité
Hygroscopic
Solubilité
Insoluble in cold water, hot water, methanol, diethyl ether, n-octanol and acetone.

Applications

Molecular sieves, 3A is used as a desiccant in petroleum and chemical industries. It is useful for drying unsaturated hydrocarbons such as ethylene, propylene and butadiene. It is also used in the removal of water from ethanol. It finds application in the drying of certain chemicals namely ethanol, refrigerants and natural gas. It plays an important role in selective adsorption of water in insulated glass (IG) and polyurethane. It has been considered as a general-purpose drying agent in polar and non polar media.

Notes

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