Abstract
The invention discloses a synthesis formula of an ultrahigh cross-linked styrene macroporous adsorbent and a process route thereof. In the synthesis formula, one unit of 80 percent divinylbenzene is auto-polymerized, two units of methylbenzene are taken as a pore-foaming agent, and the ultrahigh cross-linked styrene macroporous adsorbent is prepared by performing post-linking twice.
Description
Technical field that the present invention belongs to:
The synthesis technique that the invention belongs to artificial synthetic high polymer adsorbent in the chemical field reaches the macroporous adsorbent of complying with its making.
The prior art background:
The process route that prior art is made macroporous adsorbent comprises that polymerisation, chloromethylation and Fu Shi cross-linking reaction are called for short the back cross-linking reaction, also have a kind of single auto polymerization process route in addition.The adsorbent specific surface of making according to the polymerization technique route of prior art is no more than 600m
2/ g.And specific area is the important indicator of adsorbents adsorb performance.The specific area that improves adsorbent is that the adsorbent production technology is improved the target of being pursued.
Content of the present invention:
The objective of the invention is the existing macroporous adsorbent technology of making is reformed, the synthesis technique of invention superhigh cross-linking macroporous adsorbent reaches according to it and makes novel macroporous adsorbent.
Process route of the present invention:
Being to adopt unit content 80% divinylbenzene, is that pore-foaming agent carries out autohemagglutination with the toluene of two units, again through after crosslinkedly make high crosslinked macroporous adsorbent, its course of reaction:
Synthetic route:
The auto polymerization reaction:
High crosslinked macroporous adsorbent
Specific area 450-550m
2/ g
Back cross-linking reaction:
The crosslinked prescription in back
10g Archon: 50-60ml dichloroethanes: 1.5-2.0g ferric trichloride
Temperature: 80 ℃-82 ℃
Reaction time: 10-12 hour
The superhigh cross-linking macroporous adsorbent
Specific area: 950-1100m
2/ g
。
Changing pore-foaming agent employing toluene and normal heptane amount ratio is 150: 50 synthetic macroporous adsorbents; Change pore-foaming agent and adopt toluene and 200
#The gasoline amount ratio is 150: 50 synthetic macroporous adsorbents; Change pore-foaming agent and adopt toluene and carbon alcohol C
8-OH amount ratio is 150: 50 synthetic macroporous adsorbents; The change pore-foaming agent adopts toluene, liquid is cured and PS (polystyrene, molecular weight≤6000) amount ratio is 150: 40: 10 synthetic macroporous adsorbents;
Used divinylbenzene is a high-load, and high-crosslinking-degree 78% only has the two keys of 30-35% divinylbenzene to participate in reaction in polymerization process, the two keys that also remain 45-50% have neither part nor lot in reaction and be suspended in the sorbent structure with the surface on.
Substantive distinguishing features of the present invention is:
Created the secondary post-crosslinking process, made full use of this part and have neither part nor lot in reaction and be suspended on sorbent structure in and the surface is gone up to such an extent that two keys carry out the back cross-linking reaction, the specific area of increase adsorbent.
Marked improvement of the present invention is:
Crosslinked result behind the secondary, sorbent structure is tightr, mechanical strength good, and specific area can improve and meets or exceeds 950-1100m
2/ g, the level of suitable active carbon, micropore is very flourishing.Compare with active carbon, the present invention surpasses crosslinked macroporous adsorbent and has significant advantage:
(1) renewable, repeated use.
(2) particulate can not occur and come off, cause secondary pollution; Or make when pharmaceutical products uses and can not cause liquid medicine contamination, or the problem of thrombus and blood compatibility difference can not appear when making the adsorbent of blood perfusion.
(3) centering, small-molecule substance, the adsorption function of the compound of special band shape is very special, as: VB
12, ArAA, heroin class and amphetamine drugs etc.
