Simple Carbinol is methyl alcohol or wood spirit (taken as COH.H3), a compound of 1 atom of carbon with 1 of hydroxyl OH, and 3 of replaceable hydrogen, any one or more of which may be replaced by the same number of alcohol radicals, the name or names of which are prefixed. When only one hydrogen atom is replaced, the carbinol is a ‘primary alcohol’, as methyl carbinolCOH.H2.CH3 = ethyl or ordinary alcohol, C2H5OH; ethyl carbinolCOH.H2.C2H5 = propyl alcohol C3H7OH. When two atoms of hydrogen are replaced, the carbinol includes the ‘secondary alcohols’ as dimethyl carbinolCOH.H.(CH3)2 = secondary propyl alcohol C3H8O; methyl-propyl-carbinolCOH.H.CH3.C3H7. When all three atoms of hydrogen are replaced, the carbinol includes the ‘tertiary alcohols’, as trimethyl carbinolCOH.(CH3)3 = tertiary butyl alcohol C4H10OH, dimethyl-ethyl-carbinolCOH.(CH3)2.C2H5. The nomenclature of the complicated members as carbinols is more simple and definite than as alcohols.extracted from carbinoln.
