Abstract A method for preparing aliphatic alcohol with 24-34 carbon atoms by using cerosin of cane includes the following steps: homogeneous-saponifying cerosin in KOH butyl alcohol solution for 1-3 hr, acidifying and separating out organic phase, adding Ca(OH)2 and active carbon to decolour, filtering and recovering butyl alcohol, using ethyl alcohol to decolour and make recrystallization, adding ethylene chloride to make treatment, filtering and then drying at 60-65 deg.C to obtain high-grade aliphatic primary alcohol mixture, in which the main effective component 1-octacosanol content is about 70%.
