- Аннотация: A mechanism of the initiated nonbranched-chain pro-cess of forming 1,2-alkanediols and carbonyl com-pounds in alcohol–formaldehyde systems is suggested. The quasi-steady-state treatment is used to obtain ki-netic equations that can describe the nonmonotonic (with a maximum) dependences of the formation rates of the products on the concentration of free unsolvated formaldehyde. The experimental concentration of the free unsolvated form of formaldehyde are given at the different temperatures, solvent permittivity, and total concentrations of formaldehyde in water and alcohols. An empirical equation for calculating the free formal-dehyde concentration in alcohol–formaldehyde (including water/ ethanediol–formaldehyde) systems at various temperatures and total formaldehyde concentrations and an equation for evaluating solvent concentrations in these systems were derived. Keywords: nonbranched-chain process, free formal-dehyde, 1-hydroxyalkyl radical, formyl radical, com-peting reaction, equation.
