Patent Title: Method for preparing molecular engram CS/TEOS hybridized film by separation of phenylalanine isomer
Publication date: 2006
Publication number: CN1843598

Abstract: The invention discloses a method for preparing molecule print chitose/silicic acid carbethoxy hybridized film used to separate phenylalanine isomer of water solution. Said method comprises: adding chitose into acetate water solution whose content is 2%; mixing and filtering insoluble part with filter cloth to attain chitose solution; mixing and adding silicic acid carbethoxy into chitose solution; fully mixing, than adding L-phenylalanine water solution to be mixed for 12 hours; defoaming and filling casting liquid on the horizontally arranged clear organic glass plate horizontally to be extended and form transparent film; thermal treating the film and washing. The invention has the advantages that: the method is simple; attained molecule print chitose/silicic acid carbethoxy film has high density without significant phase separation, and it has better mechanical strength, and better separation function on phenylalanine isomer.
