Abstract Mainly because of the high sensitivity isocyanate group to atmospheric moisture, it is blocked with a blocking agent for many applications and thus kept as inert possible at room temperature (Zhang et al. in Langmuir ACS J Surf Colloids 37:12705, 2021, Meier-Westhues Polyurethane: Lacke, Kleb-und Dichtstoffe, Vincentz Network, Hannover, p 36, 2007). When exposed temperature, protective...

Chloropinane and chloromenthene, synthesized from pinene limonene, respectively, were compared with their non-halogenated analogs n-hexane for ability to solubilize natural products of interest such as ?-carotenoids, vanillin, rosmarinic acid. was six times more efficient than hexane ?-carotene solubilization. Chloromenthene 15 better hexane. Vanillin 20 soluble in chloropinane chloromenthene 3...

A highly selective electrochemical sensor modified with CuFe2O4 nanoparticles and the ionic liquid was constructed for detection of vanillin. The could recognize vanillin from its analogs possible coexistent substances. response peak current concen­tration showed a good linear relationship in range 0.01 - 300.0 μM, sensitivity 0.0923 μA μM-1. limit 0.008 μM (S/N = 3). Besides, reproducibility s...

BACKGROUND Salix aegyptiaca is known for its medicinal properties mainly due to the presence of salicylate compounds. However, it also contains other beneficial phytochemicals such as gallic acid, quercetin, rutin and vanillin. The aim of the study was to examine the redox potential, antioxidant and anti-inflammatory activity of these phytochemicals along with acetylsalicylic acid. METHODS Th...

We studied the thermal decomposition of vanillin in a low-pressure pyrolysis microreactor by photoelectron photoion coincidence spectroscopy. The products were identified isomer-selectively mass-selected threshold spectra (ms-TPES) based on Franck–Condon simulations and reference spectra. Methyl loss homolytic C–O bond fission methoxy group is initial unimolecular step. primary intermediate, 2-...
