【Abstract】 In this paper,we inversigated the Regularity between the boiling points of 1-haloalkanes （RX）and the molecule structure parameters after analysing the structure factors affecting boiling points.An empirical formula was proposed as follows: T_b=133.54n^1/2+123.49r_x^3/2-14.292n^{（1/2）r_x3/2}-279.4 Where T_b stands for the boiling points of 1-haloalkanes（RX）,n stands for the number of carbon atoms in alkyl R（n=1～20）,r_x stands for the covalence redius of X（X=F,Cl,Br,I）.The calculated values were close to obscrved values by using the formula.更多还原
