On the basis of these data and of the distribution of isomeric products obtained by hydroformylation of the two intermediate olefins, the amounts of I1 and IV derived from reactions A+ D and C+ E may be evaluated. Thus of a total of 39.5% 11,. 0.33% is due to reaction D and 1.62% to reaction E. Analogous considerations may be made for IV. By subtracting the amounts of II. owing to reactions D and E calculated in this way (from total ...
