| Abstract: | The method for the determination of n-and i-paraffins in paraffin wax, by the useof 5A molecular sieve as adsorbent,isooctane as solvent, under the condition of reflux,was discussed.Some wax samples were determined and the results were compated with that of GC.This method is simple to operat and give an accurate and precise result with the TSD less than 士1%. |
