Gel Strong-Base Anion-Exchange Resin Catalyst

in Boosting Inorganic-Reactions Induced-by OH


KP-2013OH is a gel strongly basic anion exchange resin-type catalyst of the sulphonated polystyrene series, generally as the initiator for catalyzing inorganic reactions or organic synthesis allowing traces of organics retained. Owing to its uniform and solid structure and low swelling rate after reversible ionic replacement reactions, this resin remains perform with strong resistance to osmotic shock. 

In addition to its excellent physical &chemical stability and thermostable performance, KP-2013OH is structured with fine crosslinked porosity and quite intense granular strength, which enables its nonadsorptive exclusivity of organic molecules without blocking resin pores neither interfering the reaction compositions.

Thanks to its nuclear-grade ion state OH form, KP-2013OH can be directly used in inorganic reactions that are induced by OH– where demineralization and catalysis are required or allowed. Alternatively, it can also be used in hydroxyl-driven organic reactions where small amounts of organic anions are fine to be retained for synthesis yet not plugging the pores. Or even within pure-water systems where needless of anions to be exchanged, KP-2013OH’s strong-base groups will remain auto-hydrolyzed and discharge OH thereafter.

Due to its strong-base groups, KP-2013OH proactively releases adequate OH into reaction liquid to get it initiated, by exchanging necessary anions within solution if any. In such way of discharging hydroxide ions as the initiating agent, KP-2013OH powers the degree of the reactions by catalyzing its progress more thoroughly. 

Taking advantage of its exemption from adsorbing organic composition, this premium resin model KP-2013OH is hereby most suitable for drug-synthesis, cosmetic production, chemical refining & purification process when certain organics of are required to be retained without affecting reactants composition, and most importantly, more hydroxyls are needed to expedite a great deal of synthesis yield. Moreover, it is also applicable in catalyzing F&B processing in which color and odor are allowed to be kept while desalting, softening or deashing remain in need.
