설명

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
