WebLes amines sont des composés azotés qui dérivent formellement de l'ammoniac NH3par remplacement d'un ou plusieurs atomes d'hydrogène par des groupes carbonés. Le nombre ndes atomes d’hydrogène liés à l'azote, définit la classe de l’amine. Leur découverte est due au chimiste allemand Wurtz en 1849. WebMethanal solution (also known as formaldehyde solution, or formalin) should be in good condition. Because the vapour is unpleasant, the supply of this solution for this demonstration should be kept in the fume cupboard, in a stoppered bottle.

WebThe modulus and ultimate strength of the imine bond crosslinked networks are consistently enhanced with the decrease of the molecular weight of APB precursors. In addition, APB with a higher molecular weight, i.e. a lower crosslinking degree, leads to a faster relaxation rate and a higher activation energy for network rearrangement. WebMechanistic investigations indicate that the activation of alcohols via the cooperation of Cu and γ-Al2O3 plays a crucial role in cross-coupling reactions. This reaction exhibited …

In their largest application, an oxime is an intermediate in the industrial production of caprolactam, a precursor to Nylon 6. About half of the world's supply of cyclohexanone, more than a million tonnes annually, is converted to the oxime. In the presence of sulfuric acid catalyst, the oxime undergoes the Beckmann rearrangement to give the cyclic amide caprolactam:
