A new approximation has been proposed for calculation of the general temperature integral $
\int\limits_0^T {T^m } e^{ - E/RT} dT
$
\int\limits_0^T {T^m } e^{ - E/RT} dT
, which frequently occurs in the nonisothermal kinetic analysis with the dependence of the frequency factor on the temperature
(A=A
0
T
m). It is in the following form:
$
\int\limits_0^T {T^m } e^{ - E/RT} dT = \frac{{RT^{m + 2} }}
{E}e^{ - E/RT} \frac{{0.99954E + (0.044967m + 0.58058)RT}}
{{E + (0.94057m + 2.5400)RT}}

Effective charges of atoms in tautomeric forms (enol-azo, keto-azo, hydrazo) of 3-(4-chlorophenylazo) pentane-2,4-dione (L) have been determined by MO LCAO in the Hückel approximation. The complex formation of a series of metals with L in aqueous ethanol has been investigated by potentiometric and conductometric titration. Based on the results of potentiometric
titration, the standard thermodynamic functions of complex formation have been established. They vary in the following order:
