离子液体论文答辩

不要发英文的

是不是应该说明从哪方面进行比较阿？比如：离子晶体是固态的离子液体是液态的 离子晶体导电系数比离子液体差很大 等，比较什么？

The ionic liquid is an organic cation and generally by a specific bulk volume of the asymmetric structure of relatively small inorganic anions [1,2], as in the liquid state at room temperature or near room temperature, the ionic liquid is called . Moreover, ionic compounds having such special composition and function "adjustability" [3], by changing the composition to thereby improve the properties of ions in the ionic liquid. The reason ionic liquids are widely applied in all aspects of catalysis, electrochemical synthesis, and, compared with other solvents because of its environmentally friendly wide electrochemical window, good stability and good electrical conductivity and strong properties. As people continue their studies and in-depth understanding and increasingly sophisticated production technology and environmental protection requirements, the range of applications is constantly expanding. Dimethyl sulfoxide (referred to as DMSO) is a polar high boiling point, good thermal stability, colorless and odorless sulfur-containing organic compounds. As an aprotic polar solvent that is soluble in water and soluble in organic solvents, it is also known as the "universal solvent." Its wide range of applications such as health, agriculture, antifreeze, synthetic resin, fiber and other fields. This paper was synthesized using the two-step method [C3mim] HCO3 ionic liquid, and mixed with common organic solvents DMSO, [C3mim] HCO3/DMSO mixed solution was prepared a series of different proportions, respectively, the molar ratio of 1:9,2:8, 3:7,4:6,5:5. Determination of the density in the range of 20 ~ 70 ℃ temperature, and the density of the pure ionic liquids compared. The results showed that with increasing temperature, a mixed ionic liquid density is gradually decreased in a linear relationship between density and temperature. With the increase of [C3mim] HCO3 ionic liquid content, the density of the mixture gradually increased.
