Zusammenfassung:FIELD: chemical industry. SUBSTANCE: described is method of disproportionation of mixture of fatty and resin acids by heating at 230-260 C for 1-5 hours in the presence of 0.5-2% 2,2'-thiobis-(4-methyl-6- tert-butylphenol) and iodine at 1:1-20:1 ratios to give product containing more than 1% of abietinic acid weight fractions and more than 2% of fatty acids containing unconjugated double bonds. EFFECT: disproportionation method is simple to be carried out and uses accessible catalysts. 9 ex
