일반 설명

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!

애플리케이션

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.

특징 및 장점

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
