Abstract

Objective: Nifedipine is a calcium channel antagonist of dihydropyridine. There are many methods to synthesize nifedipine, but the yield is not high. In order to find a suitable process for the synthesis and industrialization of nifedipine, thermodynamic Parameters of Nifedipine had been estimated by Group Contribution Method. Methods: the standard molar enthalpy of reaction, standard isobaric heat capacity, residual entropy, the melting temperature and the flash point temperature of nifedipine were estimated by Joback method. Results: The results show that the standard molar reaction enthalpy of Nifedipine was estimated estimated by Joback method is , standard molar isobaric heat capacity is 108800J•mol-1•K-1 and residual entropy of nifedipine estimated by Joback method is at 290.15 K and atmospheric pressure which match with the datas of experiment. However the melting temperature and the flash point temperatureof nifedipine was estimated by Joback method is 1074.02 K and 969.98 K seperately, which have large gap between the estamated datas and the reality, and still need to revise. Coclusion: the thermodynamic parameters of nifedipine can be estimated by Joback group contribution method. Its corresponding data will provide essential support for industrial design and further theoretical studies.
