EVALUATION OF STEARYL-1-ALPHA-NAPHTHYL ACETATE AS A STATIONARY-PHASE FOR GAS-LIQUID-CHROMATOGRAPHY

Stearyl-1-alpha-naphthyl acetate has been prepared in the laboratory a nd evaluated as a stationary phase for gas-liquid chromatography after characterization by chromatographic and spectroscopic techniques. Sev eral organic compounds, viz., aliphatic, aromatic and chlorinated hydr ocarbons, cyclic ethers, alcohols, ketones and esters have been used a s Lest solutes. Classification of the stationary phase according to Mc Reynolds' method, Novak's thermodynamic approach and Snyder's selectiv ity triangle has been carried out. The results reveal that the station ary phase falls in the medium polar category. Industrially important c ompounds with close boiling points are satisfactorily resolved on this stationary phase. Investigations on the stability of the stationary p hase showed that it is stable upto 140 degrees C. It is concluded that stearyl-1-alpha-naphthyl acetate can be used as a versatile, easily a vailable and cheap stationary phase for GLC.
