| Abstract: | The topological index z x ,numbers of path p, measures s 1 and s 2 can be used to characterize the size,branching and shape of fatty ether,and the site of oxy atom in ether.With this,a quatitative formula for calculating physicochemical properties p of fatty ether is obtained,i.e. p=a 0 a 1p 1 a 2x 2/3 z a 3s 1 a 4s 2 Hence we can predict six physicochemical properties of fatty ether.It is demonstrated that the method possesses the advantage of easy computation and clear structural significance.The results are also satistactory. |
