Aluminium Oxide (Alumina)
Aluminium Oxide is another popular adsorbent used in chromatography.
- Like silica gel alumina may be regarded as a typical polar sorbent and th order of separation of compound classes on alumina and silica gel is generally similar. Carbon-carbon double bonds contribute somewhat more to compound adsorption energy on alumina as compared to silica gel, and hence compounds differing only in relative unsaturation (e.g/. Aromatic hydro carbon) are generally better separated on alumina than on other polar adsorbents such as silica gel.
- Active alumina are markedly sensitive to the differing shape of various aromatic hydrocarbons and some of the derivatives permitting an excellent separation of many aromatic isomers.
- The preferential adsorption of acidic substances on alumina offers many useful separation possibilities in the case of weak acids and this effects can be further enhances by the use of basic solvent.
- Stronger acids however tend to chemisorb on alumina, requiring the use of acid treated aluminas. Acidic and netural aluminas are useful for the separation of base sensitive materials. It shoulds be noted that separation order may change for basic, neutral and acidic aluminas and hence these aluminas should be considered as distint adsorbent subtypes.
In the separation and purification of dyes, dye-intermediates, alkaloids, steroids, lipids, amino acid, hormones, aliphatic and aromatic hydrocarbons, vitamins and other pharmaceutical intermediates.
