โฆ Synopsis
A long chain approximation is presented for the analysis of free radical mechanisms. This permits the calculation of relative concentrations on the basis of the chain propagation reactions alone and is valid for large chain lengths. An application is given to the calculation of product distributions in the high-pressure thermal cracking n-hexadecane and comparisons are made with existing experimental data. Due to the meager information on rate constants and to the limited accuracy of the data these comoarisons indicate the olausibility of the approximation but do not provide a measure of its accuracy.
