ABSTRACT:
Mono- and dibasic alkali metal periodates are prepared by reacting tri-, tetra- and pentabasic alkali metal periodates with a substance having a relative acidity value, pKa, of from 3 to 16 at a temperature of from 0.degree. to 100.degree. C at molar ratios of periodate to moles of acidic substance of 1:1 to 1:1000. The mono- and dibasic alkali metal periodates are useful in oxidizing olefins such as propylene to the corresponding oxide such as propylene oxide.
