-ol, suffix
used to form chemical terms.
1. The termination of alcoh-ol, used to form the names of substances which are alcohols in the wider sense (alcohol 5), or compounds analogous to alcohol; e.g. carbinol (methyl alcohol), methol, pseudol, glycol (2-atomic alc.), glycerol (3-atomic alc.), phenol (phenyl or benzene alc.), naphthol (naphthyl alcohol), etc. In some cases this systematic nomenclature has not displaced the name which the substance had previously received, e.g. glycerol is more commonly known as glycerin (or, commercially, glycerine).
2. From phenol, the ending has been transferred to bodies belonging to the group of phenols (which are alcohols), as anthranol, anthrol, cresol, cymenol, eugenol, thymol, and to some other phenol derivatives, as anethol, creosol, guaiacol, phenetol, phlorol, pyrogallol, veratrol, xylenol.
3. In some words -ol is a deriv. of L. oleum oil; in which case it is more systematically written -ole (now the usual form); e.g. furfurol, indol, oxindol, pyrrol, terpinol. |
