Combustion calorimetry on samples of mass less than 10 mg of substances containing iodine with a CRMT rocking-bomb calorimeter. Application to the study of p-iodobenzoic acid

We have used a CRMT rocking calorimeter associated with a microbomb to determine the enthalpy of combustion of a sample of mass less than 10 mg of a substance containing iodine. p-Iodobenzoic acid ( p-IC 6H 4CO 2H), a candidate as reference material for combustion calorimetry of substances containin...

Description
Summary:We have used a CRMT rocking calorimeter associated with a microbomb to determine the enthalpy of combustion of a sample of mass less than 10 mg of a substance containing iodine. p-Iodobenzoic acid ( p-IC 6H 4CO 2H), a candidate as reference material for combustion calorimetry of substances containing iodine, has been investigated. The value of − (3154.2 ± 1.3) kJ·mol −1for its molar enthalpy of combustion obtained with this apparatus is in very good agreement with the only literature value obtained by classical bomb combustion calorimetry.
