摘　　要：[目的]研究硅藻土在豆油脱皂中的应用。[方法]以离心脱皂油为试样,硅藻土为吸附剂,研究豆油无水脱皂的最佳条件。[结果]硅藻土用量为0.5%,吸附温度为110℃,吸附时间为25 min时,所得的油样残皂为68.5 mg/kg,残磷为1.317 mg/kg,均优于工业上水洗脱皂后的油品质量。[结论]硅藻土在豆油脱皂中的应用是可行的。[Objective] The research aimed to study application of the diatomite in soap removal of the soybean oil without water.[Method] Centrifugal soap-removal oil as test sample,diatomite as adsorbent,the optimal condition of soap removal of the soybean oil without water was studied.[Result] Under 0.5% of diatomite dosage,110 ℃ of adsorption temperature and 25 min of adsorption time,residual soap amount in obtained oil sample was 68.5 mg/kg,and residual phosphorus amount was 1.317 mg/kg,which was better than oil quality after soap removal by washing in industry.[Conclusion] It was feasible to use diatomite in soap removal of the soybean oil.
