Radiation Induced Incorporation of CO in Pure and Aqueous Methanol
نویسندگان
چکیده
Pure and aqueous methanol were used for radiation induced incorporation of CO at elevated pressure (up to 15 bar). The initial yields (G,) of the main products in pure methanol under 15 bar CO and 1 bar N 20 were found to be: G, (formaldehyde) = 3.80 and G;(glycolic aldehyde) = 2.0. For aqueous (10“ 2 mol • dm -3 ) methanol under 15 bar CO (dose: 0.557 kGy, pH — 2): the yields were G (formaldehyde) = 5.44, G (glycolic aldehyde) = 4.0 and G (oxalic acid) = 7.7. At pH = 7 the yields were essentially lower, namely: G(formaldehyde) = 3.2, G(glycolic aldehyde) = 2.0, G(formate) = 3.8 and G (oxalate) = 5.0. Probable reaction-mechanisms for the product formation are discussed.
