Thermal behaviour of thallous perchlorate

01 Feb 1975-Journal of Thermal Analysis and Calorimetry (Akadémiai Kiadó, co-published with Springer Science+Business Media B.V., Formerly Kluwer Academic Publishers B.V.)-Vol. 7, Iss: 1, pp 65-71
TL;DR: In this paper, the thermal decomposition characteristics of thallous perchlorate were investigated in nitrogen and in air using TG and DTA techniques, and it was shown that the relative amounts of the decomposition products depend upon both the temperature and the atmosphere around the sample.
Abstract: Thermal decomposition characteristics of thallous perchlorate are investigated in nitrogen and in air using TG and DTA techniques. Isothermal studies at 380°, 400°, 420° and 440° in air and in nitrogen showed that the relative amounts of the decomposition products, namely, thallic oxide and thallous chloride, depend upon both the temperature and the atmosphere around the sample. At low pressures (5×10−1 mm/Hg) there is volatilization of thallous perchlorate even at 200°.

TL;DR: In this article, DTG, and DTA studies of thallium(I) malonate, CH2(COOTl)2 [ = Tl2(mal)], using the derivatograph, have been carried out under static air and dynamic nitrogen atmospheres in the temperature range ambient to 1050°C.

TL;DR: In this paper, a systematic basis for predicting and rationalizing the reaction products of decomposing hydrated and anhydrous perchlorates is evolved by consideration of the relative values of the equivalent free energies of formation of the possible reaction products (oxides or chlorides).
