在 2 5℃加氢汽油介质中 ,将 Fe Cl3-Al( i-Bu) 3-Phen胶体催化剂的 3组分分别以单、多组分按不同配比混合成非水体系 ,考察了它们的电导率与浓度的关系。结果表明 ,Al( i-Bu) 3以缔合状态存在并解离成离子对 ,它与 Fe Cl3的作用是形成胶粒的主要反应。Phen与 Fe2 +络合有阻止 Fe2 +被还原成更低价态 ( Fe+ ,Fe0 )的作用。适当过量的 Al( i-Bu) 3形成双电层 ,使催化剂胶粒稳定 ,同时将 Fe3+还原成 Fe2 +。
In the hydrogenated gasoline medium at 25 ℃, the three components of FeCl3-Al (i-Bu) 3-Phen colloidal catalyst were mixed into single-component and multi- Relationship between conductivity and concentration. The results show that Al (i-Bu) 3 exists as an association state and dissociates into an ion pair. Its interaction with FeCl3 is the main reaction to form micelles. Phen and Fe2 + complexes prevent Fe2 + from being reduced to the lower valency state (Fe +, Fe0). Appropriate excess of Al (i-Bu) 3 forms an electrical double layer, stabilizing the catalyst micelle and simultaneously reducing Fe3 + to Fe2 +.
