Application:	Potassium iodide may be used as a catalyst in the following processes: • Conversion of aromatic primary amines to the corresponding nitro compounds in the presence of tert-butyl hydroperoxide as oxidant. • Conversion of aryl halide to aryl iodides in the presence of nickel catalysts. • Preparation of sulfonated oxindoles from activated alkenes and sulfonylhydrazides in water and in the presence of 8-crown-6 and tert-butyl hydroperoxide.
Features and Benefits:	• Increased efficiency – Eliminate time and effort of loosening hardened powders • Safety – Avoid risks of using tools of force to break up clumps • Economy – Faster preparation and solvation increase productivity and reduce costs • Assured quality – Excellent, expert-tested quality with no anti-caking agents • Flexible volumes – Available from research amounts to scale-up quantities
General description:	Potassium iodide is a water soluble inorganic salt that can be prepared by reacting hydrogen iodide and potassium bicarbonate. Redi-Dri^™ technology eliminates clumping and the need for complicated procedures to keep your salts free-flowing. Keeping your salts dry helps improve your results by giving accurate measurements and easier-to-handle salts and buffers. Rather than drying your salts in an oven or desiccator or breaking them apart manually, Redi-Dri^™ ensures that your salts will remain easy-to-use for months without worrying about anti-caking agents. Even after repeated openings you can be assured that your results are always accurate. Redi-Dri^™ saves you time, energy and money by keeping your salts usable for longer!
