Chemical Properties
solid
Uses
Polyaromatic adsorbent for small hydrophobic compounds, surfactants, pharmaceutical manufacturing, phenols, chlorinated organics, pesticide removal and recovery, and organic removal from aqueous food streams.
Uses
Amberlite
? XAD4 was used:
- in rapid fractionation technique
- as sorbent for HPLC analysis
Uses
Polyaromatic adsorbent for small hydrophobic compounds, surfactants, pharmaceutical manufacturing, phenols, chlorinated organics and organic removal from aqueous food streams. It is impregnated with KCN or NaCN, has been used for the conversion of aromatic acyl chlorides to acyl cyanides and of formation of trialkylsilyl chlorides to the silyl cyanides.
Definition
AMBERLITE(R) XAD-4 is a non-polar divinylbenzene-styrene copolymer macroporous ion exchanger; also described as divinylbenzene-ethylvinylbenzene
General Description
Nonionic macroreticular resin that adsorbs and releases ionic species through hydrophobic and polar interactions; usually used under isocratic conditions.
