Of a solvent (or solute): having a tendency to remove a proton from most solutes (or solvents). Opp. protogenic a.2 Also ˈprotophile (rare), such a substance.
1930N. F. Hall in Jrnl. Chem. Educ. VII. 787 The terms protophilia and hydrophilia have been proposed to describe the tendency of a molecule to unite with proton, and it would seem that some such word as protophile, forbidding as it is, would arouse less prejudice than the term base used in such a broad and subversive manner. Ibid. 792 Next there is the basic strength, or protophilic tendency of the solvent. 1931,1940[see protogenic a.2]. 1953Audrieth & Kleinberg Non-Aqueous Solvents ii. 33 Amphiprotic solvents occupy a position intermediate between those of marked protophylic [sic] character, such as ammonia and the amines, and those of distinct protophobic character, such as acetic and hydrogen fluoride. 1969[see protogenic a.2]. 1973E. J. King in Covington & Dickinson Phys. Chem. Org. Solvent Syst. iii. 334 Ethanolamine and dimethyl sulphoxide are basic or protophilic solvents. |
