## Abstract The thermal decomposition of the title compound has been studied in the gas phase in the temperature range of 584β634 K. The decomposition was found to be a firstβorder homogeneous process yielding 2βmethylbutaβ1,3βdiene and formaldehyde. The rate constants obtained at 11 temperatures w
In an extension of our studies on the thermal decomposition of Amadori compounds (l), we have identified 2,3-dihydro-3,5-dihydroxy-6-methyl-4&pyran-4-one (Ia) as the major solid product that is volatilized during the pyrolysis of l-deoxy-l-(k-prolino)-&fructose at 138"/1 mm. The structural assignmen
