规格用途
备注说明 | Aquivion® PW79S coarse, acid powder based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) CF2=CF-O-(CF2)2-SO2F produced by Solvay. The resulting perfluoropolymer's functional groups are in their sulfonic acid form, SO3H. Aquivion® PW79S is chemically-stabilized (denoted by the S-suffix).Aquivion® PW79S is characterized by a low equivalent weight and a high ionic exchange capacity. It can be used as is under conditions where conventional exchange resins have shown insufficient chemical resistance.Due to its superacid functionality with many active groups, it can be used either directly or as an ingredient of composite structures active as a heterogeneous catalyst. This encompasses a wide range of organic syntheses and respective reaction mechanisms. It is insoluble in water, acid or bases and in most solvents unless extreme conditions are applied.Furthermore Aquivion® PW79S can be dissolved in some organic solvents to produce ion exchage capacity membrane. Proper organic solvents are dipolar aprotic such as N-ethyl-2-pyrrolidone (NEP) and dimethyl sulfoxide. To facilitate the dissolution, slightly increase the temperature to 50-60°C.Please visit Aquivion.com for more information. |
