How to remove 5% of the moisture in isopropyl alcohol

Azeotocette...99.5% have no problem

High molecular super hydrate adsorbent, spherical, mixed with material, and then removal of the adsorbent.The adsorbent can be regenerated and used repeatedly.

Distillation, our methanol can evaporated 99.5%

4A molecular sieves, first burn dry in the muffle, vacuum oven and add vacuum or dryer to cool after cooling.

If the amount is small, dry can be dried with a type A molecular sieve at room temperature.

In industrial production, molecular sieves or azeotropic water can be used; the laboratory can be used in chemical reactions.

See how much you want to remove water, you can try more than 1% to stir directly with sodium hydroxide, it is necessary to discuspect 0.5% or less, can be removed by chemical method, for example
