ABSTRACT:
The conventional water-resistant silica or alumina plate for thin layer chromatography is converted into a reverse-phase thin layer chromatographic plate by tri-(lower alkyl)silylating the adsorbent in situ. The adsorbent layer containing the tri-(lower alkyl)silyloxy group is found to be superior to either of the known adsorbent layers containing mono- or di-(lower alkyl)silyloxy groups, or mono-(higher alkyl)silyloxy groups. Optimum conditions for performing a method for preparing the plate are also disclosed.
