XPell is a ground-breaking product that indicates and prevents the formation of peroxides in alkyl ethers. The pellets are composed of a high surface area insoluble support coated with an inorganic material that is also insoluble in organic solvents. Peroxides are continually removed via chemical reactions between the pellets and peroxide. The pellets reduce the peroxide groups resulting in an alcohol functionality and water. The water is expected to remain absorbed on the pellets. Given that long-term storage of peroxide generating solvents can result in ppm concentrations of peroxides, the organic products are expected to be much less than one ppm under normal conditions and result in negligible changes in overall solvent purity. In comparison, reagent grade diethyl ether typically contains 250 ppm BHT as inhibitor. Thus XPell is a significant improvement over solution-based stabilizers where both the inhibitor and resulting reaction products with the peroxides remain in solution.
80 grams (sufficient for treating up to 8 L of solvent)
For each liter of solvent, add one tablespoon (approx 10g) of XPell. XPell neutralizes peroxides present in the solvent and peroxides that form over time. The solvent is protected as long as XPell pellets remain dark blue. A color change to a yellow/pale color indicates that the protection is exhausted. Once this change occurs, add more pellets to the solvent until the color of the additional pellets remain dark blue.
