Technical field
The present invention relates to a kind of polymeric adsorbent and synthetic method thereof, specifically, be meant a kind of pyrrolidone-base modified composite function absorption resin and preparation method thereof.
Background technology
In recent years, the complex function polystyrene resin is owing to have characteristics such as high-specific surface area, various surface chemistry, high mechanical strength, increasingly extensive water body purification, extract drugs, the chromatographic separation technology field of being applied to.The macroporous ion exchange resin of relevant pyrrolidone containing base, existing report is applied to chromatographic separation, but this resin is without crosslinking reaction later, and specific surface area is very low usually, and is relatively poor to the nonpolar organic matter absorption property, and the mechanical property of resin particle is not high yet; And general polymeric adsorbent can only pass through hydrophobic interaction fractionation by adsorption organism, to the adsorptive power of hydrophilic organics hydrophilicity a little less than.Calendar year 2001, Nanjing University applied for " a kind of synthetic method with superhigh cross-linking weak basic anion exchange resin of dual-use function " patent (patent No. ZL0134143.2), its key step is: a) utilize whiteruss, the 200# solvent oil is made pore-creating agent, use magnesiumcarbonate, gelatin, one or more mixtures such as polyvinyl alcohol are made dispersion agent, vinylbenzene is made monomer, divinylbenzene is made linking agent, peroxidation benzene first phthalein is made initiator, adopt suspension polymerization, synthetic low crosslinking degree macroporous polystyrene, select steam distillation for use or use acetone according to pore-creating agent character then, lower boiling gasoline extracting pore-creating agent, air stream drying gets the low cross-linking macropore polystyrene resin (ps) again, following abbreviation Archon pearl body; B) soak Archon pearl body with Archon pearl body weight 4-7 chloromethyl ether doubly, zinc chloride with Archon pearl body weight 30-50% is made catalyzer, carry out chloromethylation at 36-42 ℃, reach more than 18% until cl content, take out most chlorination mother solution, water or organic solvent are washed remaining chlorination mother solution in the most resin, and be dry then, get dry chloroethyl crosslinked polystyrene, following abbreviation chlorine ball; C) at chloromethylation low cross-linking polystyrene in cross-linking process after one's death, make solvent with oil of mirbane or substituted-nitrobenzene etc., with Louis's acid as catalyst such as zinc chloride, iron trichloride, tin tetrachloride, consumption is the 5-30% of chlorine ball weight, be warming up to suitable temp, determine reaction end by control resin residual chlorine content; D) after the reaction, take out most reaction mother liquor, with one or more organic solvent washing polymeric adsorbents in ethanol, methylal, acetone, the methyl alcohol, directly use the dimethylamine amination then, the dimethylamine consumption is 1-3 a times of chlorine ball, can make the superhigh cross-linking weak basic anion exchange resin of a series of different specific surface areas, different exchange capacities.This patent has related to employing dimethylamine modification polymeric adsorbent and has obtained the composite function super high crosslinked resin of amine-modified weak base in the resin synthesis step, but does not mention at resin surface grafting pyrrolidone functional group.
Literature search shows that pyrrolidone-base modified complex function adsorption resin and preparation method thereof is not seen bibliographical information.
Summary of the invention
The purpose of this invention is to provide pyrrolidone-base modified composite function absorption resin and preparation method thereof.Resin of the present invention has both wetting ability and lipophilicity, has overcome general polymeric adsorbent and can only pass through the organic shortcoming of hydrophobic interaction fractionation by adsorption, has the dual function of absorption and ion-exchange.
Technical scheme of the present invention is as follows:
A kind of pyrrolidone-base modified composite function absorption resin, its structural unit is as follows:
Can from structural unit, find out the existing wetting ability pyrrolidone of this resin functional group, hydrophobicity vinylbenzene skeleton is arranged again.This resin can carry out ion exchange (or electrostatic interaction) by pyrrolidone group and metal ion or easily protonated organic acidity compound, carries out the hydrophobic adsorption of Van der Waals between hydrophobicity that also can be by the skeleton of resin own and the organic hydrophobic part.
Described a kind of pyrrolidone-base modified composite function absorption resin, its specific surface area are 300-1500m
2/ g, exchange capacity are 0.1-5.0mmol/g.
A kind of preparation method of pyrrolidone-base modified composite function absorption resin may further comprise the steps:
A) chlorine ball (chloromethylation low cross-linking macroporous polystyrene one divinylbenzene resin) is swollen in oil of mirbane, substituted-nitrobenzene, ethylene dichloride or the orthodichlorobenzene solvent, add zinc chloride or iron trichloride, tin tetrachloride as catalyzer, temperature is 20-120 ℃, control resin residual chlorine content is that 4-15% determines reaction end, obtains the polystyrene-divinylbenzene polymeric adsorbent of different degree of crosslinking;
B) steps A) after the reaction, take out most reaction mother liquor, residual solvent and the catalyzer of one or more organic solvent flush awaies in water or ethanol, acetone, methylal, the methyl alcohol; Make swelling agent with trichloroethane, oil of mirbane, substituted-nitrobenzene, ethylene dichloride, orthodichlorobenzene, benzene or toluene then, consumption is 2-6 a times of weight resin; Under 30-90 ℃ temperature, add pyrrolidone function reagent, consumption is 0.5-3 a times of weight resin, further react with resin surfaces externally and internally residual chlorine methyl, reaction times is 2-24 hour, can make the pyrrolidone-base modified composite function absorption resin of serial different specific surface area, different exchange capacities.
The preparation method of above-mentioned a kind of pyrrolidone-base modified composite function absorption resin, steps A) in, the consumption of oil of mirbane, substituted-nitrobenzene, ethylene dichloride or orthodichlorobenzene is 2-6 a times of chlorine ball; In the crosslinking reaction process, the amount of catalyzer zinc chloride, iron trichloride or tin tetrachloride is the 4-50% of chlorine ball weight behind the chlorine ball.Substituted-nitrobenzene has been meant substituent oil of mirbane herein, and substituting group is mainly alkyl.
The preparation method of described a kind of pyrrolidone-base modified composite function absorption resin, normally, under the identical situation of other conditions, the pyrrolidone reagent dosage is many more, reaction times is long more, temperature of reaction is high more, and the specific surface area of prepared composite function resin is low more, and loading capacity is high more.
