Abstract

PERTESSIS-KEIS has studied the yield of organic ³⁸Cl from the reaction ³⁷Cl(n,γ)³⁸Cl in binary mixtures of CCl₄ and alcohols. KONTIS and URCH suggested an independent binary model to interpret the data, however, none of their data agree with the model over the whole range of concentrations. In this paper we suggest a new model based on the formation of organic ³⁸Cl by two precursors, one independent on the media (failure to bond rupture), while the other depends on the concentration of the two components in the binary mixture (reactions of hot and thermalized ³⁸Cl). Our model fits all the alcohols studied by PERTESSIS-KEIS^1,2 over the whole range of concentration: (Equation Presented) where Y is the organic yield of ³⁸Cl in the mixture, Y₀ is the yield for pure CCl₄ (zero molar fraction of the alcohol), m_A and m_B are the molar fraction of the alcohol and CCl₄, respectively, and or is a parameter. A plot of 1(Y ₀-Y) vs. m_A/m_B was found to be a straight line for all the six alcohols studied by PERTESSIS-KEIS.
