摘要： 在离子交换膜电解槽内,将电解溴离子生成的溴单质作为氧化剂,使羟基新戊醛变成羟基新戊酸.研究了反应温度、pH、反应物浓度及阳极电位对电流效率和选择性的影响.结果表明,槽内式间接电氧化法制取羟基新戊酸的电流效率和选择性都较高,电流效率可达91.4%.选择性一般在90%以上.

关键词: 羟基新戊醛, 羟基新戊酸, 溴离子, 间接电氧化

Abstract: In an electrolytic cell with an ion exchange membrane, Br- was oxidized to Br2, which was used as an oxidant to oxidize hydroxypivalaldehyde to hydroxypivalic acid. The effects of temperature, pH, anode potential and concentration of reactants on current efficiency and selectivity was explored. The results indicate that the current efficiency and the selectivity of the reaction for forming hydroxypivalic acid are very high, the highest current efficiency is 91.4%, the selectivity was generally greater than 90%.

Key words: Hydroxypivalaldehyde, Hydroxypivalic acid, Bromide ion, Indirect electrooxidation
