Resin ion-exchange resins

Fine chemicals These are produced in small volumes and purchased on the basis of chemical composition, purity and price. Examples are chloropropylene oxide (used for the manufacture of epoxy resins, ion-exchange resins and other products), dimethyl formamide (used, for example, as a solvent, reaction medium and intermediate in the manufacture of pharmaceuticals), n-butyric acid (used in beverages, flavorings, fragrances and other products) and barium titanate powder (used for the manufacture of electronic capacitors).

In spite of the great variety of bonded phases, many of which have been developed to replace silica gel and resinous ion-exchange resins, prominence has been attained mainly by those with nonpolar l ates. The reason for this is, of course, the bro scope of RPC, which could be explored and exploited because efficient and stable stationary phases had been available. [Pg.236]

The addition of alcohols to alkenes is also catalyzed by boron trifluoride-hydrogen fluoride, but the reaction proceeds only under vigorous conditions and the yields are generally low.394 Recently, the etherification of alkenes has also been achieved industrially by using acidic montmorillonite395 and macroporous sulfuric acid resins (ion-exchange resins).396...

Ion Exchange Resins. Ion exchange resins, regular commercial products, were obtained from the Chemical Process Co., Redwood City, Calif. [Pg.183]

Blending of two independent ion-exchange resins would result in the development of a composite ion-exchange resin. Ion-exchange resin which incorporates an inert material in its matrix is also classified as a composite resin. Usually, the inert material... [Pg.93]

Ion Exchange Resins. Ion exchange resins may be used to selectively remove ionic components from supercritical fluids in much the same manner as from liquids. [Pg.433]

According to the chemical strength between the exchangeable ions and the functional groups in the resins, ion exchange resins can be classified as (7,8,12) ... [Pg.265]
