Description
Technical field
The invention belongs to chemical technology field, relate to a kind of polymeric adsorbent and preparation thereof, for a kind of equipment that is applied to pharmacy industry and preparation method thereof, specifically is macroporous absorbent resin of a kind of antibiotic separate, dedicated and preparation method thereof especially.
Background technology
The synthetic method of macroporous absorbent resin mainly includes the pore-foaming agent cross-linked polymeric that participates in and two kinds of methods such as secondary cross-linking of reacting based on functional group.The former is as U.S. Rohm﹠amp; Series such as Amberlite XAD4, XAD7 that Haas company produces and XAD16, domestic also have similar products such as LS16 and a LS18 etc.; The latter such as domestic resin NKA, XDA and H series etc.Facts have proved that the pore structure uniformity of the resin that the cross-linked polymeric method that adopting has pore-foaming agent to participate in is synthesized is relatively poor, and adopts the aperture of the secondary cross-linking method synthetic resin that reacts based on functional group less relatively.This two resinoid is used for from zymotic fluid isolated molecule amount when the antibiotic of 500-1200 scope, and its equilibrium adsorption capacity can only reach 100-130ku/g usually.On the other hand, this two resinoid also has certain adsorption capacity to being present in impurity such as pigment in the zymotic fluid and albumen, thereby cause the antibiotic concentration of separate targets thing and all basic demands of inaccessible follow-up separation process of purity in its stripping liquid, this perhaps become this technology at present as yet not at home the erythromycin production field obtain industrialized major reason.
It is to prepare the conventional method of passing through cross-linked network polymer (IEN) mutually that two nets pass through cross-linking polymerization mutually; see in the synthetic field of ion-exchanger to be used for the synthetic of synthetic chelating resin and amphoteric ion-exchange resin, as document (SCI, 1994 more; 09,1310).Do not see at present the bibliographical information that is used for macroporous absorbent resin.
From the conventional method of streptomyces erythreus zymotic fluid separate red mycin is the butyl acetate extraction process, and the greatest drawback of this technology is exactly separative efficiency lower (≤68%), loss of extractant and energy consumption is higher, contaminated wastewater is serious etc.Adopt resin absorption technique to replace extraction process then to be expected to overcome these defectives, but require the adsorption capacity of resin and ability removed in the selection of pigment higher relatively, inaccessible this requirement of common polymeric adsorbent.
Summary of the invention
The objective of the invention is to provides a kind of macroporous absorbent resin that is applicable to the antibiotic separate, dedicated at from the basic demand of streptomyces erythreus zymotic fluid separate red mycin to adsorption and separation material, discloses its preparation method simultaneously.
The present invention uses for reference passes through improvement and the raising that the cross-linked network synthetic technology is used for the polymeric adsorbent performance mutually, on the basis of the synthetic polymeric adsorbent of conventional crosslinking copolymerization, pass through cross-linking polymerization mutually by the two nets of secondary and reach and improve resin pore structure uniformity, give the suitable polarity inner surface of resin, improve resin to the adsorption capacity of separate targets thing and purpose optionally simultaneously according to the antibiotic polar requirement of separate targets thing.
The macroporous absorbent resin of antibiotic separate, dedicated of the present invention is characterized in adopting 2～4 kinds of specific function monomers and crosslinking agent under peroxide initiator, water and inorganic salts existence condition, carries out the two nets of secondary with styrene-divinylbenzene macropore copolymerization bead (St-DVB Archon) and passes through the crosslinking copolymerization reaction mutually and synthesize; The prescription of styrene-divinylbenzene macropore copolymerization bead (St-DVB Archon) is by weight:
5～20 parts of styrene (St)
