Free Unsolvated Formaldehyde in Solutions: Influence of Temperature, Solvent Permittiity, and Total Formaldehyde Concentration

What is it about?

Addition of 1-hydroxyalkyl free radicals to unsolvated formaldehyde in alcohol–formaldehyde solutions with nonbranched-chain formation of 1,2-alkanediols.

Why is it important?

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 formaldehyde 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.
