Synthesis of a Reactive Surfactant Ammonium Methyl Ricinoleic Acid Sulfate 反应型表面活性剂-蓖麻油酸甲酯硫酸铵的合成
The result of SDS-PAGE certificated the method 6% octanoic acid combined with ammonium sulfate got the highest purity, the next was alginic acid sodium combined ammonium sulfate. SDS-PAGE和低压层析的结果证明,用6%辛酸硫酸铵法提取IgY的纯度最好,其次是海藻酸钠硫酸铵法。
Transparent emulsifier systems were prepared by using SDS, Ammonium Methyl Ricinoleic Acid Sulfate and SE-10N as surfactant, among Which the Ammonium Methyl Ricinoleic Acid Sulfate and SE-10N were reactive surfactants. 使用SDS、蓖麻油酸甲酯硫酸铵和SE-10N为乳化剂配制了透明的微乳液体系,其中蓖麻油酸甲酯硫酸铵和SE-10N为反应性表面活性剂。
The pseudo-ternary phase diagrams of MMA/ AA/ SDS-H2O, Ammonium Methyl Ricinoleic Acid Sulfate/ MMA/ H_2O and SE-10N/ MMA-AA/ H_2O were figured out. The structure types of these microemulsions were characterized by the shapes of conductivity curves. 绘制了MMA/AA/SDS-H2O体系、蓖麻油酸甲酯硫酸铵/甲基丙烯酸甲酯/H2O体系和SE-10N/MMA-AA/H2O体系的相图,用电导率仪分析了微乳液的结构类型。
A large amount of ammonium sulfate as by-product was formed in this process. And brings equipment corrosion, high cost etc. Vapor-phase Beckmann rearrangement over solid acid catalysts can avoid ammonium sulfate, however, because of its high reaction temperature, catalysts can easily inactivate. 该重排工艺副产大量的硫酸铵,成本高,存在严重的设备腐蚀问题。气相Beckmann重排能避免硫酸铵的形成,但反应温度较高,导致催化剂容易积碳、失活。
