A THERMAL-ANALYSIS STUDY UPON THE TRANS-I SOMER, SIN-ISOMER, TRANS-ISOMER AND TRANS-ISOMER, ANTI-ISOMER, CIS-ISOMER OF TETRADECAHYDROACRIDINE

The paper studied, by thermogravimetric and thermodifferential analysi s, the trans, sin, trans (4 a alpha, 8 a alpha, 9 a beta, 10 a alpha) and trans, anti, cis (4 a alpha, 8 a alpha, 9 a beta, 10 a alpha) isom ers of the tetradecahydroacridine. The analysis of these products ther mogravimetric and thermodifferential curves showed: the temperature th e thermal decomposition is initiated at, the temperature where the the rmal decomposition reaction rate is the highest, the degree of compoun ds decomposition, as well as the kinetic parameters - activation energ y and kinetic order of the thermal decomposition reactions.
