NOUVELLE METHODE de DETERMINATION des INDICES de REFRACTION d'ALCANES PERHALOGENES

Article abstract of DOI:10.1016/S0022-1139(00)80937-9

We propose a new formula such as (*) in order to calculate the refractive index (n) of perhalogenated alkanes containing N_i atoms i(C,F,Cl, or Br), at a given temperature.The contributions K_i of each element are determined at different temperatures.This method which has been tested on a series of compounds whose experimental values of the refractive index are given is the literature, leads to results which are much nearer reality than those given by different methods known so far.
