olationn.

Brit.

/əˈleɪʃn/, U.S.

/əˈleɪʃ(ə)n/

Origin: Formed within English, by derivation. Etymons: ol adj., -ation suffix.

Etymology: < ol adj. + -ation suffix. Compare olate v.Though often attributed to N. Bjerrum and to E. Stiasny the word has not been found in their publications.

Chemistry and Tanning.

Conversion of a complex into an ol form; the linking of metal atoms by hydroxyl ligands.Frequently with reference to chromium compounds used in tanning.

1948 J. H. Bowes in Progress Leather Sci. 1920–1945 xxvi. 524 Stiasny..termed this process ‘olation’ and postulated that hydroxy groups react immediately with acid whereas ‘ol-groups’ only react after deolation.
