Enantioselective Multidimensional Gas Chromatography of Some Secondary Alcohols and Their Acetates from Banana

Using enantioselective M D G C the enantiom eric d istribution o f alkan-(alken-)2-yl-acetates from bananas is achieved. A fter simple acetylation their corresponding alcohols 2-pentanol, 2-hexanol, 2-heptanol and (Z)-4-hepten-2-ol respectively are also exactly stereodifferentiated by the same method. All com pounds investigated esters as well as alcohols exhibit a rem arkable excess o f the (5...

Paper Chromatography: Separation and

The example of column chromatography (Figure 1) demonstrates the typical features found in this analytical technique. The diagram shows an experiment where a two-component mixture is subjected to column chromatography. The column is packed with a solid material called the stationary phase. A liquid solvent or eluting solution is poured into the column and completely wets the solid packing mater...

Paper Chromatography

In this laboratory exercise we will separate and identify the cations in an aqueous mixture that possibly contains Fe 3+ , Ni 2+ or Cu 2+ salts. The separation will be achieved using Paper Chromatography. Identification of the cations will be affected by simultaneously running separate solutions, each containing a single salt of these ions, through the chromatographic system and comparing the r...
