Flow injection analysis of 5-(hydroxymethyl)-2-furaldehyde in honey by a modified winkler method
(2016-01-01)
One of the quality indicators for honey is 5-(hydroxymethyl)-2-furaldehyde (HMF), which is formed during the heating or aging of honey. The International Honey Commission recommends three methods for the determination of ...
Structure and UV-induced photochemistry of 2-furaldehyde dimethylhydrazone isolated in rare gas matrices
(Pergamon-Elsevier Science Ltd, 2012-11)
In this work, a combined matrix isolation FTIR and theoretical DFT(B3LYP)/6-311++G(d,p) study of 2-furaldehyde dimethylhydrazone (2FDH) was performed. According to calculations, two E and two Z conformers exist, the E forms ...
