The o-cresol is one of the VOCs toxic compounds, it is used as pharmaceutical intermediates, reagents, custom synthesis and as a solvent, disinfectant and chemical intermediate for a wide variety of products including resins, paints and textiles.
À Propos de CRAPC
Le centre de recherche scientifique et technique en analyses physico-chimiques (CRAPC) a été fondé en 1992 par un groupe de chimistes, chercheurs ambitieux, Algériens. Au fil du temps, le centre a donné une contribution significative avec un grand succès dans le domaine de la chimie par le biais de la promotion de l'innovation et l'investissement dans des thèmes de recherche accentués qui ont un impact positif sur les communautés scientifique, sociale et industrielle.
Le centre comprend quatre principales divisions de recherche; à savoir la Division Santé, Division Sciences des Matériaux, Division Produits Naturels et Sciences des Aliments et Division Chimie de l’Environnement.
Olive oil excels by its nutritional and medicinal benefits. It can be consumed without any treatment. However, its quality can be altered by inadequate storage conditions or if it is mixed with other kinds of oils.
Condensation of compounds containing active methylene group with aromatic aldehyde (piperonal) in the presence of BaO on KF without a solvent under microwave irradiation is an efficient synthetic approach to methysticin and derivatives of kavalactones (4-methoxy-6-styryl-pyran-2-ones).
The semiconducting properties of the heterojunction CuO/ZnO, synthesized by impregnation method from nitrates, are studied for the first time to assess its feasibility for the hydrogen production under visible light, an issue of energy concern.
In this work, the relationship between the structure and the radical scavenging activity of seven hydroxycoumarins and their sulfured analogs was investigated for the first time by density functional theory calculation in the gas phase, benzene, and water.
We formulate for the first time new [Alizarin-poly(4-vinylpyridine)-mica] inorganic@organic pH dependent pigmentary materials.
Ethyl 2-oxocyclohexanecarboxylate has undergone smooth condensation with arylamines under ethanol. The corresponding b-enaminoesters compounds were obtained in good yields. These compounds were then refluxed in biphenyl ether to attain the respective substituted tetrahydroacridin.
Olive oil flavour represents the most important factor that influences customer’s perception for quality.
