Definition of superacid in English:

superacid

noun ˈsuːpərasɪdˈso͞opərˌasəd

Chemistry

A solution of a strong acid in a very acidic (usually non-aqueous) solvent, functioning as a powerful protonating agent.
〔化〕过量酸，酸性过多
Example sentencesExamples
- Solid superacid catalysts have many advantages such as an easy separation of products from catalyst, the repeated use and regeneration of catalysts, as compared with liquid superacids.
- What makes superacids difficult is that chemistry's going on, the making and breaking of bonds.
- Urea and substituted ureas exhibit a weak basicity and may bind a superacid in the form of a quarternary ammonium salt.
- Typical solid Brönsted superacids include titanium dioxide: sulfuric acid and zirconium dioxide: sulfuric acid mixtures.
- Others were Bronsted superacids such as HSO3F or the extremely strong superacids obtained by combining e.g. HSO3F or HF with SbF5.

Derivatives

superacidity

noun

Chemistry

A similar approach has been successfully used to elucidate the Brønsted acid sites of sulfated zirconias, which have been linked to the superacidity and catalytic activity of the material.
Example sentencesExamples
- These beads, when reacted under the above disclosed conditions of fluoroalkylsulfonation or fluoro, perfluoroalkylsulfonation, produce surface modified beads of high Bronsted superacidity.
- These versatile liquids exhibit Brønsted and Lewis acidity and superacidity; they include liquids ranging from hydrophobic to hydrophilic, and from water-sensitive to air stable.
- Hammett's first great contribution to chemistry was the concept of superacidity and his acidity function.
- As the range of superacidity covers over 11 logarithmic units of the Hammett acidity scale, the mechanistic behavior of small alkanes vary accordingly.
