Brit.

/ˌmɛθəˈnɒlᵻsɪs/, U.S.

/ˌmɛθəˈnɑləsəs/

Origin: Formed within English, by compounding. Etymons: methanol n., -lysis comb. form.

Etymology: < methanol n. + -lysis comb. form.

Chemistry.

Alcoholysis using methanol.

ΚΠ

1912 J. J. Sudborough in E. Thorpe Dict. Appl. Chem. (ed. 2) III. 83/2 Alcoholysis,..the reaction with methyl alcohol is termed ‘methanolysis’, and that with ethyl ‘ethanolysis’.

1921 Science 26 Aug. 175/1 A proximate determination of the composition of five commercial fish oils was made by converting a kilo of each of the oils into its methyl esters by a modified Haller methanolysis.

1971 B. Buck tr. H. Ludewig Polyester Fibres x. 359 It is more practicable to carry out methanolysis of the polyester under pressure with suitable catalysts.

1996 Chem. in Brit. Mar. 11/4 The best process looks to be methanolysis, using methanol to return the PET to its constituent monomers.

This is a new entry (OED Third Edition, December 2001; most recently modified version published online March 2022).
