An alcohol containing two hydroxyl groups in its molecule.
- ‘Macrodiols with different thermal characteristics were prepared using ring-opening polymerization of cyclic diesters or lactones with a low molecular weight diol as an initiator.’
- ‘These materials are based on the polymerization reaction of a diol with a diisocyanate.’
- ‘The epoxide hydrolases are a family of enzymes that hydrate simple epoxide to vicinal diols and arene oxides to transdihydrodiols.’
- ‘Biocatalysts from unique South-African biomes are employed to produce a wide range of single enantiomer chiral epoxides and diols in highly efficient, environmentally friendly processes.’
- ‘They are the result of a reaction between a diacid (such as terephthalic acid) and a diol (such as ethylene glycol).’
1920s: from di- ‘two’+ -ol.
