通过电化学方法合成了 WO(OMe)_4,WO_2(OE_t)_2,WO_2(OP_r~i)_2三种钨(Ⅵ)的烷氧基化物.确定了在 R—OH(R=Me,E_t,P_r~i)体系中以金属钨为阳极,铂为阴极电解合成钨的烷氧基化物时,其反应的活性依次为 Me>E_t>P_r~i.最佳支持电解质为 Bu_4NBr.证明不能通过电化学合成法制备正丁醇、丙烯醇的钨烷氧基化物.研究了产物的热分解性质,结果表明,钨的烷氧基化物在热解过程中直接分解为 WO_3、烯烃和醇.测定了阳极钨的动电位扫描循环伏安曲线.
The alkoxylated compounds of WO3, WO2 (OE_t) _2 and WO_2 (OP_r ~ i) _2 were synthesized by electrochemical method. P_r ~ i) system of tungsten as anode, platinum cathode electrolysis synthesis of tungsten alkoxylates, the reaction followed by the activity of Me> E_t> P_r ~ i. The best supporting electrolyte Bu_4NBr. Prove that electricity can not be passed Chemical synthesis of n-butanol, propylene alcohol Tungsten alkoxylation of the product of the thermal decomposition of the results showed that the tungsten alkoxylate pyrolysis process directly into WO_3, olefins and alcohols measured Anodic tungsten potentiodynamic scanning cyclic voltammetry curves.
