Preparation of α-terpineol and perillyl alcohol using zeolites …
The preparation of α-terpineol by direct hydration of limonene catalyzed by zeolites beta was studied. The same catalyst was used to prepare perillyl alcohol by isomerization of β-pinene oxide in the presence of water. The aim was to optimize the reaction conditions to achieve high conversions of starting material and high selectivity to …

3 Ways to Separate Alcohol and Water
2. Place the alcoholic liquid into a container. As water expands when it freezes, make sure that your container is large enough to hold the expanded liquid without bursting. The water content of the liquid will expand, but the amount of alcoholic beverage will be much less, due to the extraction of the water.

Removal of TBA from Water
Adsorption. Adsorption through a packed bed appeared to be the best option for removing TBA from water. In the process of adsorption, a solid adsorbent whose surface has a special affinity for the solute is used to remove the solute from a liquid or a gas6. For this experiment the solute (TBA) would be removed from a liquid (water) by …

What are zeolites? | How do zeolite catalysts work?
The cage-like structure of zeolites makes them useful in all sorts of ways. One of the biggest everyday uses for zeolites is in water softeners and water filters. In ion-exchange water softeners, for example, hard water (rich in calcium and magnesium ions) is piped through a column filled with sodium-containing zeolites. The zeolites trap the ...
