hydroln.
/ˈhʌɪdrɒl/ 1. Chemistry. [ < -hydrol (in benzhydrol n. at benzo- comb. form 1).] Any substituted derivative of benzhydrol (diphenylcarbinol), (C6H5)2CHOH; esp. Michler's hydrol (see Michler n.).

2. Chemistry. A name suggested for the simple water molecule, H2O, as a basis for the systematic nomenclature of its polymers, (H2O)n.

1900 W. Sutherland in London, Edinb. & Dublin Philos. Mag. 50 460 I propose for international convenience to call H2O hydrol, (H2O)2 dihydrol, and (H2O)3 trihydrol. Steam is hydrol, ice is trihydrol, and water a mixture of dihydrol and trihydrol.
1915 W. M. Bayliss Princ. Gen. Physiol. viii. 234 It is to be supposed that the molecular forces, which permit the molecules of hydrol to press unusually closely together [in water], disappear when the new group constituting ice is formed, so that the latter occupies the greater volume.
1957 G. E. Hutchinson Treat. Limnol. I. iii. 196 Sutherland (1900)..supposed liquid water to consist of dihydrol H4O2 with trihydrol H6O3 in solution... Other workers believed that hydrol H2O was also present, at least near the boiling point.
3. [perhaps < hydrol- (in hydrolysis n.).] A dark viscous liquid of unpleasant taste left as a mother liquor when starch is subjected to acid hydrolysis and dextrose is allowed to crystallize out.
