How To Synthesis Adsorbent Resin?

The adsorption resin is mainly formed by suspension polymerization, and the pores are formed inside the resin through the addition of the porogen, followed by rinsing, sieving and the like.

1.Non-polar adsorbent resin
Mainly use styrene and divinylbenzene as raw materials, choose the appropriate porogen and dosage.

2. Medium polarity adsorbent resin

The acrylate monomer is mainly introduced into the non-polar adsorption resin, so that the resin structure has a certain polarity.

3. Polar adsorbent resin

It mainly contains a polar group, a nitrile group, a sulfone group, an amide group, and an amino group.

A.  adsorbent resin with Nitrile group
Polymerization of acrylonitrile and divinylbenzene

B.  adsorbent resin with Sulfone group
It is a low crosslinked polystyrene sphere which is crosslinked by thionyl chloride.

C.  adsorbent resin with Amide group
The nitrile-containing adsorption resin is obtained by aminolysis of ethylenediamine; it can also be prepared by aminoacylation of an amino polystyrene sphere by acetic anhydride.

D.  adsorbent resin with Amino group
Similar to the preparation method of the strong base anion exchange resin, different kinds ammonia can be used in the amination to prepare resins with different polarities.
