Composition comprising an iodofluorocarbon compound

A composition comprising at least 99.5% by weight of an iodofluorocarbon compound A and at most 0.5% by weight of at least one compound B chosen from water, HF, HI, IF5, I2, O2, CO2, CO and nitrogen or a mixture thereof;

• said iodofluorocarbon compound A being of formula (I) (R1)(R2)C(I)(R3) or of formula (II) (R1)(R2)C═C(I)(R3);
• wherein R1, R2 and R3 are, independently of one another, selected from the group consisting of H, F, I, a C1-C10 alkyl radical optionally substituted with at least one fluorine or iodine atom, a C3-C10 cycloalkyl radical optionally substituted with at least one fluorine or iodine atom, a C2-C10 alkenyl radical optionally substituted with at least one fluorine or iodine atom, a C3-C10 cycloalkenyl radical optionally substituted with at least one fluorine or iodine atom, and a C6-C10 aryl radical optionally substituted with at least one fluorine or iodine atom;
• on condition that at least one of the substituents R1, R2 or R3 is F or is a radical as defined above comprising at least one fluorine atom and on condition that the iodofluorocarbon compound A is not CF3I, wherein said composition comprises at most 10 ppm of HI, at most 10 ppm of HF, at most 10 ppm of IF5, and at most 10 ppm of L, each by weight based on the total weight of the composition.
