- Аннотация: A mechanism of the initiated nonbranched-chain process of forming 1,2-alkanediols and carbonyl compounds in alcohol–formaldehyde systems is suggested. The quasi-steady-state treatment is used to obtain kinetic equa-tions that can describe the nonmonotonic (with a maximum) dependences of the formation rates of the prod-ucts on the concentration of free unsolvated formaldehyde. The experimental concentration of the free un-solvated form of formaldehyde are given at the different temperatures, solvent permittivity and total concen-trations of formaldehyde in water and alcohols. An empirical equation for calculating the free formaldehyde concentration in alcohol–formaldehyde (including water/ethanediol–formaldehyde) systems at various tem-peratures and total formaldehyde concentrations and an equation for evaluating solvent concentrations in these systems were derived. Keywords: free formaldehyde, 1-hydroxyalkyl radical, formyl radical, equation.
