Abstract
Kinetics of the thermolysis of potential nitrification inhibitors base d on the derivatives of 3(5)-methylpyrazole (MP), 1-carbamoyl-3(5)-met hylpyrazole (CMP), 1-hydroxymethyl-3(5)-methylpyrazole (HMP), and 3(5) -methylpyrazolyl phosphate (MPP), have been studied by thermogravimetr y. Thermal stability is increased by substitution at the nitrogen atom in the series MPP > CMP > HMP > MP. Activation parameters have been c alculated from the thermal stability data, and methods are proposed fo r introducing the inhibitors into fertilizers and their granulation.
