摘要:
采用共沉淀法制成非均相碱性催化剂Zn-Mg-La复合氧化物, 将其用于催化甘油和大豆油甘油酯解成单甘酯(MAG)反应, 考察不同的La添加量、 焙烧温度、 焙烧时间等对催化剂活性的影响。并考察了反应温度、 醇油比、 反应时间以及催化剂用量对单甘酯收率的影响。通过XRD, SEM等表征手段, 对材料的理化性质进行分析。结果表明, 最佳的反应条件为: n(Zn):n(Mg):n(La)=1:10:1, 催化剂的焙烧时间6 h, 焙烧温度800 ℃; n(甘油):n(大豆油)=3:1, 反应温度230 ℃, 反应时间2 h, 催化剂用量为大豆油质量的0.6%, 单甘酯收率为68.1%。
Abstract:
Co-precipitation method was utilized to prepare the heterogeneous catalyst Zn-Mg-La composite oxide, which was used to catalyze the hydrolysis of soybean oil and glycerol to produce monoglyceride(MAG). The effects of La addition amount, calcination temperature and calcination time on the activity of the catalyst and the effects of reaction temperature, alcohol-oil ratio, reaction time and catalyst dosage on the yield of monoglyceride were investigated. The physical and chemical properties of the materials were analyzed by XRD and SEM. The results showed that the optimum reaction conditions were n(Zn):n(Mg):n(La)= 1:10:1, the calcination time of catalyst was 6 h, the calcination temperature was 800 ℃, n(glycerol):n(soybean oil)=3:1, the reaction temperature was 230 ℃, the reaction time was 2 h, the amount of catalyst was 0.6%, and the yield of monoglyceride was 68.1%.
