XAD7 XAD-7 acrylic ester 20-60 55 1.05 450 90

The Amberlite XAD polymeric adsorbents find application in the removal and recovery of phenols, antibiotics, chlorinated pesticides, various aromatic and nitrogen compounds from aqueous streams, hydrogen peroxide, etc.

XAD-2 and XAD-4 are nonpolar and are useful in sensitive analytical procedures for the detection and identification of narcotics and environmental organic contaminants. XAD-7 has intermediate polarity and adsorbs phenols from water or hexane; it can adsorb either hydrophobic materials from water or hydrophilic materials from nonaqueous systems.

* IRP-69 is derived from the same parent resin as CG-120 (no longer available from Rohm and Haas), but has a broader particle-size distribution. It has the following typical properties:

Min. exchange capacity: 4.3 meq/g (dry)
Functionality: sulfonic acid (strongly acidic)
Moisture content: ~ 10%
Particle size: 100 - 500 (wet mesh
Max. operating temp.: 120°C

B. Macroreticular Ion-Exchange Resins

Macroreticular resins comprise a tough, rigid, spongelike material with large, discrete pores, and have a somewhat lower capacity than gel-type resins, but can have longer operating life and effect separations not possible with gel-type resins. High-molecular-weight ions can be more completely removed from solution and more completely eluted from the resin on regeneration. Moreover, the open structure allows application with tough copolymers which would be too dense for use in a strictly gel-type system.

Moisture content: ~ 10%
Particle size: 100 - 500 (wet mesh)
Max. operating temp.: 120°C
 

2. Amberlyst Macroreticular Ion-Exchange Resins

These resins [except Grade 15 (wet)] were designed for nonaqueous applications. Their unusually high porosity and surface area expose more ionic groups in a nonaqueous system than does a geltype resin. Typical properties and applications are shown in Tables IX and X.

Additional information regarding the properties and applications of Amberlite and Amberlyst resins is available from Rohm and Haas Company. Products not available from Aldrich may be offered by Sigma Chemical Company, St. Louis. Questions concerning the application of these products to commercial processes in areas involving potential patent infringement should be directed to Rohm and Haas Company.
