ethyl maltolfragrances and flavourspyrolysisCOMPLEXESANALOGSEthyl maltol is one of the most important aromatic components in food and cigarettes because of its caramel flavour. However, the development of ethyl maltol is limited by problems such as heavy smell, low threshold, strong volatility and poor...

The invention discloses a synthesis method of an ethyl maltol intermediate, which is characterized in that ethyl chloride is used instead of bromoethane, and the solvent for Grignard reaction is 2-methyltetrahydrofuran or a mixed solvent containing 2-methyltetrahydrofuran. The invention has the ...
Nuclear magnetic resonance (1H-NMR, 13C NMR), infrared spectroscopy (IR) and high resolution mass spectrometry (HRMS) were used to confirm the target compounds. Thermal behavior of the compounds was investigated by thermogravimetry (TG), differential scanning calorimeter (DSC) and...
The chemical structures of the intermediates were characterized by mean of FTIR. The experimental results showed that the yield of ethylmaltol was greatly dependent on electrolyte, quantity of electricity, oxidation time, acidolysis time and acidolysis temperature. The appropriate conditions were ...
The complexes have been characterized by physico-chemical methods and single crystal X-ray determination. The V atom in each complex is coordinated by the NOO donor atoms of L, the OO donor atoms of L′, and one oxido group, forming octahedral coordination. The complexes were administered ...
Furthermore, according to the Py‐GC/MS analysis results, compounds 5a and 5b formed 8 and 7 pyrolysis products. The main pyrolysis products of 5a and 5b were 1‐ethyl‐2,5‐dimethyl‐1H‐pyrrole, ethyl maltol, and vanillin, which are all aroma components used to blend cigarette smoke, ...
