deprotonationn.

Brit.

/diːˌprəʊtəˈneɪʃn/, U.S.

/diˌproʊdəˈneɪʃ(ə)n/

Origin: Formed within English, by derivation. Etymons: de- prefix, protonation n.

Etymology: < de- prefix + protonation n. Compare slightly later deprotonate v.

Chemistry.

The removal or detachment of a proton (an H⁺ ion) from a molecule or atom.

ΚΠ

1951 Industr. & Engin. Chem. Feb. 387 The kinetic parameters deduced support a nonchain proton transfer mechanism, deprotonation being rate-determining.

1974 D. Nicholls Inorg. Complexes iv. 38 In absolute ethanol, complexes undergo deprotonation just as in the case of water, and alkoxides (rather than hydroxides) are formed.

2001 Chemicals & Materials from Renewable Resources (ACS Symp. Ser. No. 784) iv. 44 The first pathway would involve deprotonation of levulinic acid..at the C5-position.
