英文摘要: Crystal structure of N, N-dimethylnorephedrine hydrochloride (C11H18NOCl) (s) has been determined by an X-ray crystallography. The compound is orthorhombic P2(1)2(1)2(1). Unit cell parameters are a = 7.2486(19)angstrom, b = 9.674(3)angstrom, c = 16.952(5)angstrom; alpha = 90 degrees, beta = 90 degrees, gamma = 90 degrees, and Z = 4. Low-temperature heat capacities of the compound were measured by a precision automated adiabatic calorimeter over the temperature range from 80 to 390 K. A polynomial equation of heat capacities as a function of the temperature in the region of 80-390 K was fitted by least square method. Based on the fitted polynomial equation, the smoothed heat capacities and thermodynamic functions of the compound relative to the standard reference temperature 298.15 K were calculated with 5 K step. In addition, DSC technique was used to determine the melting process of the compound.
