摘　　要：采用二次溶剂浸取法，以氨水作为一次浸取溶剂，石油醚作为二次浸取溶剂，从甘蔗制糖滤泥中浸取天然高级烷醇，研究了反应温度、反应时间、溶剂浓度等因素对天然高级烷醇浸出率的影响．结果表明，以25％～28％的氨水溶液作为一次浸取溶剂，在90℃的条件下浸取滤泥3h，然后再用石油醚作为二次浸取溶剂，在60℃的条件下浸取上步所得的滤渣2h，高级烷醇的总浸出率可达90％左右．Leaching of policosanol from sugar refinery residue with ammonia as the first solvent and petroleum ether as the second solvent was studied. The effects of leaching temperature, leaching time and concentration of solvent on leaching rate of policosanol were investigated and optimized. The results showed that the leaching rate of policosanol approached 90% when 25%-28% ammonia was used as the first solvent to leach the original residue for 3 h under 90 ℃, and petroleum ether was used as the second solvent to leach the residue of the first step for 2 h under 60 ℃.
