碳原子序号拓扑指数( T) 不仅对环烷烃显示优良的结构选择性, 而且与其物性呈现高度相关性, 所建的沸点( Tb) 、偏心因子( ω) 和等张比容( P) 与 T 的关系依次是: Tb = 15-392 7 + 263-883 0lg T, R= 0-998 9 ; ω= - 0-045 13 + 0-06314 T0-5 , R= 0-983 9 ; Tc = 256-193 7 + 232-631 0lg T, R= 0-995 4 ; P= 14-71 + 55-89 T0-5 , R= 0-999
- Abstract:
-
The topological index ( T ) of carbon atomic ordinal number has good selectivity for cyclanes,and highly correlativity for 4 physical properties ( p ) such as boiling point ( T b),eccentric factor( ω ),critrical temperature ( T C) and parachor ( P ) of cyclanes.The regression equations between P and T are set up as follows: T b=15 392 7+263 883 0lg T,R=0 998 9;ω=-0 045 13+0 063 14T 0 5 ,R=0 983 9;T c=256 193 7+232 631 0lg T,R=0 995 4;P=14 71+55 89T 0 5 ,R=0 999 2. These regression models are authentic by the way of F test under the significance level α =0 01.The prediction results are satisfactory.
