What type of molecular sieve is used for drying and dehydrating ethyl acetate?

CNM 4A molecular sieve is widely used in the drying and dehydration of ethyl acetate. Under normal pressure, the finished product of ethyl acetate contains a certain amount of water. In the process of purifying ethyl acetate, since the product water and ethanol can form binary and ternary azeotropes with ethyl acetate, they are also partially miscible at room temperature. This brings great difficulties to the purification of ethyl acetate. In order to obtain higher purity ethyl acetate, the ethyl acetate needs to be dried and dehydrated.

CNM 4A molecular sieve has the advantages of large total adsorption capacity, high adsorption efficiency, and uniform pore size distribution. Through physical adsorption, it can remove low-concentration moisture in ethyl acetate without producing pollutants and affecting the composition of raw materials.
