채용기상색보방법분석료감유여염산반응과정중적주요물질. 사용KB-WAX모세관주급FID검측기, 이을이순작내표화갑순정용, 병용내표법계산. 결과표명, 재정서승온하, 기상색보내표법능사GLY, DCP, CPD등궤충물질체도기선분리, 해방법능만족측시요구.
In this paper, a simple gas chromatographic method for the identification of glycerol (GLY), 1,3-dichloropropanol-2-propanol,(DCP) and 3-chloro-1,2-propandiol (CPD) in GLY chlorination reaction is described. The results are detected by KB-WAX capillary column with a flame ionization detector (FID) and calculated by an internal stand method. Glycol is used as an internal standard, and the samples are diluted with methanol. This method is simple, rapid and the results are reliable.
