Macroporous Weak-Base Acrylic-Series Anion-Exchange Resin-type Catalyst
for Stimulating Organic-Synthesis Reaction-Liquids Induced by NH3- or OH-
PRODUCT DATA SHEET:
KP-3113 is a macro-porous acrylic-polymerized anion exchange resin-type catalyst, containing weak-acid N-methyl vinyl amine functional groups. Characterized by its special weak functional groups, KP-3113 is more prone to conduct reversible ionization reactions so that resins are quite readily to be desorbed thus perform high regeneration capability. Plus considering its strong binding force against inorganic and organic anions that its acrylic matrix's special groups empower as well as its excellent adsorption power of nonpolar molecules of organics that its macropore structure grants, this resin model's volumetric exchange capacity works relatively higher, including the doubled bedvolume of operating flow rate as compared to styrene-series equivalent models with other weak-base groups.
Therefore depends on what initiator anions are required for catalyzing reactions, KP-3113 can responsively releasing its carried form NH3- or after ion transition discharging enough OH- into reaction fluids, by selectively exchanging strong-acids and hydroxy radicals, along with strong negative-organic molecules therein, as far as what the catalytic degree of reactions are specified.
Taking account of its inactivity of releasing NH3- or OH- under conditions of no ion exisiting to exchange(ie. pure water systems), plus its non-adsorptivity of weak-polar organic and inorganic anions, KP-3113 is most suitable to be used in organic synthesis reaction fluids that require certain amounts of free amine or hydroxyl to be initiated or stimulated while degrees of demineralizing, decoloring, deodorizing are not hyper demanded.
In regard to the overall catalytic efficacy as compared to strong-acid resin catalyst, KP-3113 releases less amounts hydroxyl yet exchange greater volume of anions per operating flow rate. Hence taking advantage of its fair catalysis and longer service cycle, KP-1123 is often used to desalt, decolor and deodorize liquids meanwhile moderately regulating its PH for degrading acidity, in order to improve the flavor of food and beverages. More primarily, it has been also widely applied in stimulating biopharmaceutical, cosmetic, petrochemical synthetic reactions that are induced by free amine or hydroxyl, and meanwhile certain organic composition is fine to be separated without affecting its composition efficacy.
