Description

1. Technical field [0001] The invention relates to a device for preparing silica gel, in particular to a device for preparing active alkylated silica gel. 2. Background technology [0002] Active alkylated silica gel is a widely used material. It is a new material that appeared internationally in the late 1990s. It uses specially treated silica gel as a skeleton material, and has various active materials through grafting. The organic silane with functional group becomes an active material, which can be used as a carrier for catalysts, gas adsorbents, bioseparation materials, slow-release drugs and adsorption separation materials. For example, alkylated silica gel with chloropropyl group can be grafted with amine / amino group , carboxyl, pyridine, phosphoric acid, polymerized amine, cyanide and other groups to become ion exchangers that can adsorb and separate various metal ions, or to produce various complex solid catalysts by forming various complexes on this basis or graft...
