✦ Synopsis

Treatment of sucrose in aqueous solution with 0.25% oxalic acid leads to the formation of 5-hydroxymethylfurfuraldehyde and it has been shown that only the fructose half of the sucrose molecule takes part in this reaction. The conversion of glucose into 5-hydroxymethylfurfuraldehyde has been brought about by the pretreatment of its aqueous solution with alkali and the subsequent treatment with 0.25% oxalic acid. Improvements in the preparation of 5-chloromethylfurfuraldehyde from sucrose and several new 2 : 5-disubstituted derivatives of furan are described.
