英文摘要: Low-temperature heat capacities of pyrimethanil decylate (C22H33N3O2) were precisely measured with an automated adiabatic calorimeter over the temperature range from 78 to 373 K. The sample was observed to melt at(311.04 +/- 0.06) K. The molar enthalpy and entropy of fusion as well as the chemical purity of the compound were determined to be(45876 +/- 12) J/mol, ( 147.50 +/- 0.05) J (.) mol(-1 .) K-1 and (99.21 +/- 0.03)% (mass fraction), respectively. The extrapolated melting temperature for the absolutely pure compound obtained from fractional melting experiments is (311.204 +/- 0.035) K.
