| 英文摘要 | 1-dodecylamine hydrochloride was synthesized by the solvent-thermal method. the structure and composition of the compound were characterized by chemical and elemental analyses, the x-ray powder diffraction technique, and x-ray crystallography. the main structure and performance of an improved automated adiabatic calorimeter are described. low-temperature heat capacities of the title compound are measured by the new adiabatic calorimeter over the temperature range from 78 k to 397 k. two solid-to-solid phase transitions have been observed at the peak temperatures of (330.78 +/- 0.43) k and (345.09 +/- 0.16) k. the molar enthalpies of the two phase transitions of the substance were determined to be (25.718 +/- 0.082) kj center dot mol(-1) and (5.049 +/- 0.055) kj center dot mol(-1), and their corresponding molar entropies were calculated as (77.752 +/- 0.250) j center dot mol(-1) center dot k-1 and (14.632 +/- 0.159) j center dot mol(-1) center dot k-1, respectively, based on the analysis of heat-capacity curves. experimental values of heat capacities for the title compound have been fitted to two polynomial equations. in addition, two solid-to-solid phase transitions and a melting process of c12h25nh3cl(s) have been verified by differential scanning calorimetry. |
