Iridium acetate, Ir 48-54%


Chemical Properties

Melting point
Insoluble in water.


Mostly used in wax oil catalytic cracking and heavy oil catalytic cracking. The catalytic water-oxidation activity of Wilkinson's iridium acetate trimer has been characterized electrochemically and by using chemical oxidants. Results show it can function as an operationally homogeneous water-oxidation catalyst when driven with sodium periodate as a primary oxidant, but rapidly decomposes using Ce(IV) as a primary oxidant.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
