GAS CHROMATOGRAPHY OF ALKYL IODIDES

Gas chromatographic separation and identification of several alkyl iodides has been accomplished using glass columns filled with tricresyl phosphate on DMCS treated Chromosorb W. Detection by an electron capture detector (E.C.D.) permitted quantitative determination of about 10-12 grams of iodides in the presence of a large excess of hydrocarbons. Absolute and relative retention times, retention indices and sensitivities to E.C.D. were determined. The retention indices relative to n-alkanes and those relative to 1-iodoalkanes were calculated and correlated. The homologous series of 1-iodoalkanes may be suitable as a reference for the calculation of retention indices of E.C.D. sensitive substances. © 1969.
