The quaternary ammonium type strongly basic anionite is a kind of of ion-exchanger.Its purposes is very extensive.In water treatment industry, strongly basic anionite can be used for foreign ion and remove; In catalyzed chemical reaction, strongly basic anionite can be used for reactions such as Michael addition, cyanohydrination, phenolic alcohol condensation; Aspect biochemistry, strongly basic anionite can be used for alkaloid extraction, streptomysin and amino acid whose separation and purifying etc.
The common method for preparing strongly basic anionite will be used raw materials such as chloromethyl ether with strong carcinogenicity or dichlormethyl ether, as, under the condition that the Friedel-Crafts catalysts exists, make chloromethylated polystyrene, carry out amination then and make the quaternary ammonium type strong-base anion-exchange resin with chloromethyl ether and polystyrene reactant.Chloromethylation also exists problems such as polysubstituted and secondary cross-linking in addition, makes the structure complicated of chloromethyl resin, and exchange capacity descends.
(Bayer E such as Bayer; Liu X N; Tallarek U; et al.Polystyrene-immobilized Poly (ethylene imine) Chains--a New Class of Graft Copolymers, Polymer Bulletin, 1996; 37; 565-572.) reported and on polystyrene, introduced acetyl group, with formaldehyde and polyethylene polyamine the Mannich reaction takes place again, obtain the weak-base anion-exchange resin of amination.This method can't directly obtain the quaternary ammonium type strong-base anion-exchange resin, and the scope of application is limited.
(Xu Hui such as Xu Hui; Hu Xizhang; Friedel-Crafts acyl group legal system is equipped with polystyrene type anion exchange resin; the functional polymer journal; 1998.11 (4); 513-520) reported by the Friedel-Crafts acylation reaction and on crosslinked polystyrene, introduced acetyl group, prepared anion exchange resin through bromination, aminating reaction then.This method needs multistep reaction, and the exchange capacity of quaternary ammonium group is not high, and the nitrogen content of actual measurement is no more than half of theoretical value.
Summary of the invention
The present invention has overcome the problem of raw materials such as the chloromethyl ether that uses strong carcinogenicity in the prior art or dichlormethyl ether, and the method that a kind of materials safety, reactions steps are simple, can directly be made the quaternary ammonium type anion exchanger by the acyl group polystyrene is provided.
The used polystyrene of the present invention is by aromatic series mono-vinyl compound (or and non-aromatic mono-vinyl compound) and the many vinyl compounds of crosslinking agent, carries out polymerization (or combined polymerization) and prepares.
Quaternary ammonium type anion exchanger of the present invention has following structure:
The exchange capacity of this quaternary ammonium type anion exchanger is: 0.3-3.9meq/g does agent.
Quaternary ammonium type anion exchanger of the present invention can prepare according to the following steps:
(1) preparation of alpha-halogen acetylation polystyrene
Polystyrene after solvent I dissolving or swelling, is carried out the Friedel-Crafts reaction with the alpha-halogen acylting agent in the presence of catalyst.Obtain alpha-halogen acetylation polystyrene.
Described polystyrene can be linear, crosslinked, macropore or gel, the degree of cross linking is 0-60%, particle diameter is 3-1200 μ m.
(2) preparation of quaternary ammonium type anion exchanger
With resulting alpha-halogen acetylation polystyrene in (1) through solvent II dissolving or swelling 1-36 hour, then with amine at 0-100 ℃, reacted 1-24 hour, obtain the quaternary ammonium type anion exchanger.
Described solvent II is an ethanol, methyl alcohol, oxolane, N, dinethylformamide, methyl-sulfoxide, water, toluene, nitrobenzene or carrene.
Described amine is trimethylamine, triethylamine, pyridine or NH
