| Sumario: | The mechanism and kinetics of the initial formation of ethylene glycol from methanol-formaldehyde solutions by the free-radical nonbranched-chain mechanism have been developed. The experimental dependence of the radiation-chemical yields of ethylene glycol on the total formaldehyde concentration during the γ-radiolysis of methanol-formaldehyde solutions at 373–473 K is shown. The radiation-chemical yield of ethylene glycol is 139 molecules per 100 eV at a formaldehyde concentration of 1.4 mol dm−3 and T = 473 K. It has been demonstrated that the peak of this dependence is due to competition between methanol and CH2〓O for the reaction with the adduct radical HOCH2CH2O•. |
