Summary 1. A study has been made of the effect of raw-material composition on the yield and composition of acids, in the example of oxidation of petroleum paraffin waxes containing 91.2 and 73.4% n-alkanes. The yield of technical mixed water-insoluble acids, based on the wax processed, is 82.3 and 84.2% by weight, respectively. The respective yields of C5−C20 distilled acids with respect to the technical mixed acids are 68.3 and 64% by weight, and with respect to the 100% acids are 63 and 57.2%. 2. The C10−C16 and C17−C20 acids obtained by oxidation of waxes containing 91.2 and 73.4% alkanes contain (respectively) unsaponifiables 0.5 and 2.3, 1.0 and 4%; iso-acids, 8.3 and 5.2, 14.2 and 8.9%; dibasic acids, 2.2 and 4.1, 3.6 and 5.5%; total amount of impurities, including unsaturated acids and keto-acids, 19.2 and 25.1, 28 and 35.4%.
