Application of 3A molecular sieve in isopropyl alcohol dehydration

Isopropyl alcohol is an important chemical raw material and organic solvent, widely used in the chemical and pharmaceutical industries. The industrial production process produces a large amount of mixed waste liquid of isopropyl alcohol and water. It is of great significance to achieve complete separation of isopropyl alcohol and water.

3A molecular sieve has a strong adsorption effect on the moisture in isopropyl alcohol, has a good regeneration effect, and can directly obtain high-concentration isopropyl alcohol. The adsorption and dehydration of isopropyl alcohol by 3A molecular sieve can directly obtain high-concentration isopropyl alcohol, and the water absorption of 3A molecular sieve has little relationship with the state of isopropyl alcohol (gaseous or liquid). The adsorption of pure isopropyl alcohol by 3A molecular sieve The amount is closely related to the adsorption state, and is small when adsorbed in gaseous state. Nearly a hundred experiments have confirmed that molecular sieves have good regeneration effects, long service life, and are easy to operate.

Since 3A molecular sieve can dehydrate isopropyl alcohol vapor, it can be operated in conjunction with an ordinary distillation tower to reduce consumption.
