摘要：

The processes of thermal decomposition of yttrium(III) tris(dipivaloylmethanate) (Y(dpm)3) vapour and its mixtures with oxygen were investigated by using the two-temperature variant of the double-chamber Knudsen cell, with mass spectrometric recording of the gas-phase composition within the temperature range 150-degrees-650-degrees-C. The threshold temperatures of the stability of the complex vapour were determined. The temperature dependence of the rate constant was obtained for the thermolysis of Y(dpm)3 vapour, and the effective activation energy of the process was determined. Qualitative data were obtained on the influence of Cu(dpm)2 vapour on the thermolysis of Y(dpm)3 vapour in oxygen atmosphere.
