Decomposition of 5 hydroxymethyl 2 furaldehyde under gamma irradiation

Abstract

"An investigation into the effects of gamma irradiation decomposition of 5-hydroxymethyl-2-furaldehyde (HMF) revealed HMF to be resistant to radiation catalyzed decomposition. A 1.0 normal solution of HMF was irradiated at a dose rate of 4.1 x 10⁵ Rads/hr to a total dose of 8.2 x 10⁶ Rads from a 5000 Curie ⁶⁰Co source. a total of 31 per cent of the HMF decomposed in a zero order reaction, although it was found the HMF decomposed completely under cadmium shielded irradiation in a nuclear reactor with some neutrons present. The reaction rate constant was found to be 4.8 x 10⁻³ moles liter⁻¹ seconds ⁻¹. Formic and levulinic acids, ordinary products of HMF hydroysis, were not detected as constituents of the irradiated liquid phase. The only detectable product was a polymeric material which formed and then decomposed under a continued irradiation. HMF was analyzed in its free state using gas chromatography with SE-30 10 per cent by weight, column packing and also Carbowax 20M column packing at temperatures between 150 and 200⁰C"--Abstract, page ii.
