- Abstract
Thermogravimetry, differential scanning calorimetry, and flow methods were used to investigate thermal properties of a series of cobalt(II) β-iminoketonates [R2C(NR1)CHC(O)R2]. The consecutive order of their volatility was determined. The complexes do not decompose up to melting and do not undergo phase transitions. For the complex (R1 = Н, R2 = Me) the temperature dependence of sublimation ln (p/p0) = 32.02 ‒ 16822/T(K) at 402.6‒433.7 K was measured and the values of ΔsublH°Т* = 140±4 kJ/mol and ΔsublS°Т* = 266±10 J/(K·mol) were calculated.
