摘要:
Hexafluoroacetone or its hydrate is produced in a higher yield than that of the conventional process (1) by oxidizing a heptafluoroisobutenyl ether with ozone or (2) by thermally decomposing an octafluoroisobutyl ether or a heptafluoroisobutenyl ether in the presence of oxygen and an activated carbon catalyst.
