In this work, experimental dissociation data for clathrate hydrates of isopentane + carbon dioxide and isopentane + methane are reported in the temperature ranges of (273.5-282.4) and (275.5-285.7) K, respectively. The experimental data were generated using an isochoric pressure-search method. The reliability of this method is examined by generating new dissociation data for clathrate hydrates of isopentane + methane and comparing them with the experimental data reported in the literature. The acceptable agreement demonstrates the reliability of the experimental method used in this work. The experimental data for all measured systems are finally compared with the corresponding experimental data in the absence of isopentane reported in the literature to identify its promotion effects.
