The extraction conditions of higher aliphatie alkanols from beeswax by improved saponification hydrolysis were studied and discussed in this paper. By screening materials and opimizing the influencing factor of saponification hydrolysis, the optimal extraction conditions were researched and obtained. Chinese beeswax from Ganzhou was used as material, aviation kerosene was used as solvent and reaction time was 4.5 hour. As a result, the yield rate of higher aliphatic alkanols could be reached up from 33% to 35%. From the analytic identification and quantification of the higher aliphatic alkanols by C,C,the content of octacosanol and triacontanol was found to be up to 12% and 70% respectively.
