Preparation of Novel Room-Temperature Molten Salts by Neutralization of Amines

Hirao, Michiko, Sugimoto, Hiromi, Ohno, Hiroyuki·2000·Journal of The Electrochemical Society

Abstract

Examples of a new class of onium salts bearing the tetrafluoroborate anion ( BF 4 − ) were prepared by neutralization of the corresponding amines. This method greatly simplifies the preparation of many organic molten salts. Some of the resulting neutralized amines displayed an ionic conductivity greater than 10 − 2 S cm − 1 at room temperature. The largest ionic conductivity was observed in 2‐methyl‐1‐pyrroline neutralized by HBF 4 . In addition, the ionic conductivity above the melting point is well described by the Vogel‐Tamman‐Fulcher formula. There is a correlation between the ionic conductivity of neutralized amines and of the corresponding alkylated onium salts having the same heteroaromatic rings. These neutralized amines are convenient models of onium salts having high ionic conductivity. © 2000 The Electrochemical Society. All rights reserved.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
