Heat of formation of hydroxymethyl [PDF]

open access: possibleThe Journal of Physical Chemistry, 1993
Threshold photoionization mass spectrometry has been used to measure the appearance energy for the formation of CH 2 OH + from methanol. A value of 708.5±0.8 kJ-mol -1 is obtained for the 298 K cationic heat of formation, which results in a corresponding heat of formation for the hydroxymethyl radical of -18.9±1.0 kJ mol -1 .

Isolation of Phytotoxic Phenols and Characterization of a New 5-Hydroxymethyl-2-isopropoxyphenol from Dothiorella vidmadera, a Causal Agent of Grapevine Trunk Disease.

Journal of Agricultural and Food Chemistry, 2018
Polyphenols were characterized from Dothiorella vidmadera (DAR78993), which was isolated from a grapevine in Australia. In total, six polyphenols were isolated including a new polyphenol characterized by a spectroscopic method (essentially NMR and HR ...

Facet Effect of Single-Crystalline Pd Nanocrystals for Aerobic Oxidation of 5-Hydroxymethyl-2-furfural

, 2017
Single-crystalline Pd nanocrystals enclosed by {111} or {100} facets with controllable sizes were synthesized and originally employed as catalysts in the aerobic oxidation of 5-hydroxymethyl-2-furfural (HMF).

Basicity-Tuned Hydrotalcite-Supported Pd Catalysts for Aerobic Oxidation of 5-Hydroxymethyl-2-furfural under Mild Conditions

, 2016
An environmentally benign and homogeneous base-free route for 5-hydroxymethyl-2-furfural (HMF) aerobic oxidation to 2,5-furandicarboxylic acid (FDCA) in water was reported using Mg–Al–CO3 hydrotalcite-supported Pd nanoparticles (xPd/HT-n) as catalyst ...

Hydroxymethylation of pyrimidine mononucleotides with formaldehyde

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1967
Abstract The 5-hydroxymethyl derivatives of the 5′-mononucleotides corresponding to uracil and cytosine, both in the ribose and deoxyribose series, have been obtained by the direct coupling of formaldehyde to the pyrimidine ring, catalyzed by base.

Catalytic transfer hydrogenation of biomass-derived 5-hydroxymethyl furfural to the building block 2,5-bishydroxymethyl furan

, 2016
An efficient process for the catalytic transfer hydrogenation of biomass-derived 5-hydroxymethyl furfural (HMF) to 2,5-bishydroxymethyl furan (BHMF) is presented using ethanol as a hydrogen donor and solvent over low-cost ZrO(OH)2. A HMF conversion of 94.
