Some neutralized amines are obtained as liquid. Analyses of their ionic conductivity results have provided some interesting. Figure 19.2 shows the Arrhenius plots of... 

Figure 19.2 Arrhenius plots of the ionic conductivity for neutralized amines shown in Table 19.1.

Note that Tg s of neutralized amines in Table 19.2 are quite low—even below —80°C. Accordingly, these salts generally show high ionic conductivity. Some of the obtained salts show excellent ionic conductivity around 10 Scm at 25°C. Figure 19.2 provides the Arrhenius plots of ionic conductivity for these neutralized salts. The ionic conductivity of the salts of cases 1, 2, 3, 4, 13, and 21 is very high, which can be expected from their (and Tg, data not shown here). Among these... 

Although neutraUzed amines are useful as models of onium type salts, they are not classified among typical ionic liquids. We have already seen that there is a similarity between the thermal properties and ionic conductivities of neutralized amines and quatemized onium salts [5]. Here we investigate the relationship of ionic conductivity between neutralized and alkylated imidazolium ionic liquids having BF. ...
