1. The mechanism of conversion of furfuryl alcohol to methyl levulinate, has been studied, and a more satisfactory mechanism suggested than the one proposed by Pummerer. 2. The use of 2 ,4-dini trophenylhydrazine hydrochloride as a reagent for the study of ring opening in the furan series, has been developed. 3. Some older methods for the recovery of carbonyl compounds from their derivatives, namely distillation with aqueous sodium hydroxide (10%), or sodium carbonate (saturated), chromic acid oxidation and ozonolysis, have been applied to 2,4-dinitrophenyl hydrazones. 4. A method bas been proposed for the synthesis of derivatives of ð-methoxy-levulinaldehyde-dimethylal. 5. The assumption that ð-methoxy-levulinaldehyde-dimethylal is an intermediate in the conversion of furfuryl alcohol into methyl levulinate, as proposed by Pummerer, has been shown to be incorrect.
