Plutonium "carbonate reaction with, phosgene

Larger samples are only partially chlorinated, since molten PuClj prevents the reaction going to completion [234], whereas plutonium(Hl) oxalate is completely converted into PuClj at 600-650 C, but the product is contaminated with carbon [234]. Plutonium(III) "carbonate", in contrast, is quantitatively converted between 4(X> and 550 C [234]. Phosgene has been used in a laboratory study upon the reprocessing (by chlorination) of neutron-irradiated uranium fuels [1491].
