Molecular Sieve for Solvent Drying The number of ways is available to dry the range of solvents. Methanol, Ethanol, Isopropyl alcohol, Di Chloromethane, Chloroform, Toluene etc. are some of the commonly used solvents that need to be performed drying or dehydrating process to get the pure solvents. Such solvents can be further used as the useful compounds in different applications. Among the different ways, molecular sieves are considered as the effective method to adsorb unwanted compounds, water or gases through solvent drying processes. 3A & 4A molecular sieves are the adsorbents used to remove water and other impurities from the solvents. For certain applications, organic liquids are required to be dried, due to this reason drying agent are used for the desired outcome. This is what 3A & 4A molecules in the form of beads and pellets perform.
