摘要: 以草酸和氯化胆碱为原料，采用减压蒸发法制备深共熔溶剂，研究草酸与氯化胆碱的物质的量比对所制备的深共熔溶剂外观状态和折射率的影响，以及温度对深共熔溶剂黏度和电导率的影响.结果表明：用该方法制备的深共熔溶剂为微黄、透明、黏稠、均一的稳定液体，随着草酸与氯化胆碱的物质的量比的减小，深共熔溶剂的折射率逐渐增大；在同一草酸与氯化胆碱的物质的量比下，深共熔溶剂的黏度随温度的升高而减小，电导率则随温度的升高而增大；在同一温度下，深共熔溶剂的黏度随草酸与氯化胆碱的物质的量比的减小而增大，电导率则随物质的量比的减小呈先增大后减小的趋势.

Abstract: Using oxalic acid and choline chloride as raw materials, the deep eutectic solvent was prepared by vacuum evaporation.The effect of the molar ratio of oxalic acid and choline chloride on the appearance and refractive index of the deep eutectic solvent, and the effect of temperature on the viscosity and conductivity of the deep eutectic solvent were studied.The results showed that the deep eutectic solvent prepared in this experiment were all yellowish, transparent, viscous and uniform stable liquid.With the decrease of the amount of substance ratio of oxalic acid and choline chloride, the refractive index of the deep eutectic solvent increased gradually.At the same amount of substance ratio of oxalic acid and choline chloride, the viscosity of the deep eutectic solvent decreased with the increase of temperature.The conductivity of the deep eutectic solvent increased with the increase of temperature.At the same temperature, the viscosity of the deep eutectic solvent increased with the decrease of the amount of substance ratio of oxalic acid and choline chloride,while the conductivity of the deep eutectic solvent increased first and then decreased with the decrease of the amount of substance ratio of oxalic acid and choline chloride.
