【Abstract】 Based on the characteristics of molecular structure,the quantitative relation between critical temperature and molecular structure of alkenes is studied,a method is developed which can be used to predict the critical temperatures of alkenes from the information of molecular structure,and a computer program is developed,The results show that the predicted crtical temperatures agreed with the literature data satisfactorily,the mean relative deviation is 0.97% for 169 kinds of allkenes.更多还原
