Description

Macro porous crosslinking sulfonic acid per-fluoroalkyl polystyrene ion exchange resin and preparation method thereof
Technical field
The present invention relates to a kind of functional high molecule material and preparation method thereof, particularly macro porous crosslinking sulfonic acid per-fluoroalkyl polystyrene ion exchange resin and preparation method thereof.
Background technology
Large hole cation exchanger resin has the history of four more than ten years, is widely used in gas phase or liquid phase adsorption catalysis, ion-exchange, fields such as sewage disposal.Zeo-karb mainly contains superpower acid type, strong acid type, several big classes of weak-type.Superpower acid type Zeo-karb mainly is a perfluorinated sulfonic acid ion exchange resin, as the Nafion series plastics of Dupont company production; Strongly acidic cation-exchange is mainly the polystyrene type sulfonate resin, as Rom ﹠amp; The Amberlyst series plastics that Hass company produces; The weak-type Zeo-karb is mainly polystyrene carboxylic acid, series plastics such as phosphoric acid.
Large hole cation exchanger resin is made up of many agglomerating microballoons and the macropore that is scattered here and there on every side thereof; It is big to have specific surface, and the active centre is easy to approaching, and exchanging equivalent is big, is easy to produce advantages such as low price; Its shortcoming be acidity a little less than, thermostability is relatively poor.The relatively poor root of these resin thermostabilitys is to take off sulfonic acid more than 120 ℃ easily.The thermostability and the research report of strength of acid that are intended to improve them are a lot.One of them method is exactly the binding ability that increases sulfonic group or contain sulfonic acid group substituting group and phenyl ring, such as introduce drawing electron groups such as halogen, nitro, ethanoyl on phenyl ring, takes off the purpose that the sulfonic acid temperature reaches raising resin thermostability thereby improve; And for example sulfonic acid group is connected on the phenyl ring by fatty carbon chain, also can improve the thermostability of resin, but the strength of acid of resin dies down obviously thereupon; Again with its sulfonation, so also can improve the thermostability of resin behind the spherome surface of polyethylene being received polystyrene or polyvinyl chloride that also has; The somebody directly with fluorine gas with macroporous polystyrene sulfonate resin perfluorination, the perfluor super acid resin that generates has both excellent thermostability and naturally near the superpower acidity of Nafion. but fluoridize with element fluorine is inflammable, explosive, the operation of severe toxicity, the degraded of main chain are also unavoidable.
Nafion perfluorinated sulfonic acid series plastics thermostability is better than the macroporous cross-linked polystyrene sulfonate resin, has been widely used in fuel cell membranes, organic catalysis etc.Perfluorinated sulfonic acid ion exchange resin swelling in polar solvent is difficult to swelling in non-polar solvent.When as solid acid catalyst, because specific surface area is little, the active centre is not accessible, thereby catalytic activity is lower, has limited the scope of catalytic applications.Add that synthesis technique is loaded down with trivial details, blowdown is more, reason such as cost an arm and a leg, and it is restricted greatly that it is applied.In recent years, in order to overcome the above-mentioned shortcoming of Nafion, Dupont company successfully develops the Nafion resin attached to SiO 2The matrix material of nano grain surface, its specific surface area are thousands of times of Nafion, have improved catalytic activity greatly, but exchanging equivalent is reduced to about 10% of Nafion greatly.
As mentioned above, but the degree of closeness of strength of acid, thermostability, active center, production difficulty or ease are four big important indicators of comprehensive evaluation ion exchange resin.Macroporous cross-linked polystyrene sulfonate resin and perfluorinated sulfonic acid ion exchange resin respectively have superiority, but none satisfies whole four indices.In decades, Zeo-karb qualitative leap almost do not occur with regard to its structure type.Above-mentioned two resinoids are independent development separately, only improves the shortcoming of self in the finite space, does not but have the breakthrough of essence on method and product, and this is the bottleneck place of current Zeo-karb development.
Summary of the invention
The present invention provides a kind of macro porous crosslinking sulfonic acid per-fluoroalkyl polystyrene ion exchange resin and preparation method thereof.Its objective is perfluor and two not fluorine-containing resinoid constitutional featuress are combined together, produce the fluorine-containing sulfonic acid ion exchange resin of a kind of part, make it have the advantage of macroporous polystyrene type sulfonate resin and perfluorinated sulfonic resin concurrently and overcome both shortcoming.A promptly synthetic class has superpower acidity concurrently, high thermal stability, and bigger serface, the active centre is accessible, is easy to the Zeo-karb of advantages such as synthetic and low price.
