Lanthanide oxides reaction with, phosgene

LANTHANIDE AND ACTINIDE HALIDES AND OXIDE HALIDES 9.3.1 Reactions of phosgene with lanthanide oxide halides... [Pg.363]

The reaction of lanthanum(III) oxide fluoride, a-LaOF, with phosgene has been investigated as a function of time and temperature (430, 500 and 680 C) by t.g.a., followed by product analysis and characterization by powder X-ray diffraction [113]. This is a much more thorough study than those described above for the lanthanide oxide chlorides, and the results are summarized in Fig. 9.9. All the fluoride ends up as LaF (thus no significant quantities of COCIF or COFj can be formed), and the major product at each temperature is LaOCl. The product analysis is consistent with the following sequential reactions occurring [113] ... [Pg.364]
