aprotic, a. Chem.|eɪˈprəʊtɪk|
[ad. G. aprotisch (J. N. Brönsted 1930, in Zeitschr. f. angew. Chem. XLIII. 232/1): see a- 14, proton, -ic.]
Of a liquid, esp. a solvent: having little or no tendency to accept or donate protons; neither protogenic nor protophilic.
1931Chem. Rev. VIII. 194 A solvent of opposite or aprotic character is represented by benzene, which neither gives up nor takes up protons to any considerable extent. 1940[see protogenic a.2]. 1965Phillips & Williams Inorg. Chem. I. xv. 556 In ‘aprotic’ solvents the acid-base concept may be extended to regard those substances which generate the solvent cation (e.g. NO+ in NOCl..) as ‘Lewis’ acids, and those which generate the solvent anion (e.g. Cl- in NOCl..) as ‘Lewis’ bases. 1973[see protic a.]. 1983Chemical Week 25 May 37/1 The aprotic solvents are expensive and the purification equipment that is necessary to recover them entails a considerable capital investment. |
