Synthesis, characterization and thermal behaviour of 2,6- and 3,4-dimethylpyridinium and 2,4,6-trimethylpyridinium octamolybdates

Thermal Decomposition and Dehydration Kinetics of Tetra(piperidinium) Octamolybdate Tetrahydrate in Air

“…[5][6][7][8] In 1981, Gili et al 5 performed a comparative study on the thermal and kinetic stabilities of dichromates and octamolybdates of organic bases, finding that the compounds show several steps of decomposition controlled by a random nucleation mechanism. In 1984, Martinez et al studied the thermal decomposition of anilinium octamolybdate dihydrate by thermogravimetry at isothermal 6 and non-isothermal 7 conditions.…”

“…In 1984, Martinez et al studied the thermal decomposition of anilinium octamolybdate dihydrate by thermogravimetry at isothermal 6 and non-isothermal 7 conditions. In 1985, Lorente et al 8 synthesized 2,6-and 3,4-dimethylpyridinium and 2,4,6-trimethylpyridinium octamolybdates, studied their thermal decomposition by means of thermogravimetry, and calculated the kinetic parameters for the first step of thermal decomposition of the two dimethyl derivatives from a single thermogravimetric curve at a heating rate of 5 ℃/min. However, to the best of our knowledge, there is no report on the thermal decomposition of isopolymolybdates using a multiple linear regression method under non-isothermal conditions.…”
