| Abstract The first part of this study involve preparationand identification of somep- cresol derivatives C14H14N2O (4-MePAMeP), C13H11ClN2O (4-CPAMeP),C14H14N2O2(4-OMePAMeP).In the second part including the study of gas chromatographic behavior of theprepared compounds on liquid- stationary phases fused silica (BP10 ),Zebron (FFAT),Polysiloxane (OV-5) capillary column by using Gas Chromatography apparatus with Flame Ionization Detector FID,N2- as carrier gas with optimal flow rate30 cm3/min ; with (10)0Cincrement depend on maximum temperature operation on column and the temperature of the column inlet and detector were higher than the separation column by (25,50)0C respectively .The results indicate that the chromatographic behavior was normal ,showing decrease of specific retention volume with increase of column temperature ,and a linear relation between logarithm of specific retention volume and the reciprocal of absolute temperature appears depending onClausius –Clapeyron equation , the ∆ S0 , ∆H0 , ∆ G, were calculated after that the resolution (RS) ,number of theoretical plates(N) andheight equivalent to theoretical plate(HETP) were also calculated. | ||
