METHODS Insulin loaded poly ( lactic co glycolic acid) nanoparticles ( INS PLGA NPs) w as prepared by a double emulsion solvent evaporation method. 方法用复乳溶剂挥发法制备了胰岛素乳酸羟基乙酸共聚物纳米粒(INSPLGANPs);
The effects of loaded catalyst weight, styrene/ H2O2 molar ratio, acetone ( as solvent)/ styrene molar ratio, reaction temperture and time on activity were investigated. 考查了催化剂的用量、苯乙烯/H2O2(mol)比和溶剂丙酮/苯乙烯(mol)比、反应温度以及反应时间等反应条件对该催化氧化反应的影响。
99. 99% purity was achieved for the outgoing products carried by both the loaded solvent and the aqueous raffinate at both ends. 在连续运行的五个月中,水相和有机相两个出口都稳定得到了99.99%纯度的产品。
The off line analysis and finger feedback control for the separation of lanthanum and cerium in multistage mixer settlers have been performed. 4N and 3N purity of products was achieved for the outgoing products carried by both the loaded solvent and the aqueous raffinate at both ends. 采用离线分析手动增量PI反馈控制,在混合澄清槽镧铈分离的两个出口都稳定得到了高于4N和3N纯度的产品。
