Third, the mixed solution was put in water bath of 50°C for 1h to obtain the first network via the amine‐anhydride click reaction. Afterward, the second network was formed by photopolymerization. Finally, the

2.5.3.5.1 The Polonovski reaction The Polonovski reaction occurs when an amine oxide reacts with an acylating agent.39 The accepted mechanism involves proton removal to give a nitrogen ylide which loses acetate (using acetic anhydride) which attacks the carbon adjacent to the nitrogen atom giving...
Metal, such as zinc, containing biobased poly(ester amide) is prepared by the polycondensation reaction of linseed oil fatty amide diols, phthalic anhydride, and zinc acetate (Zafar et al., 2007). Waterborne poly(ester amide)s are also prepared from different vegetable oils such as castor ...

Amide is a derivative of carboxylic acid and can be made in several ways. The common ways include nucleophilic substitution reaction between amine and anhydride or acid chloride, and the coupling reaction between amine and carboxylic acid.Answer and Explanation: ...

Question: explain why only one amine hydrogen which is get substituted by acetyl group eventhough acetate anhydride is used excessively in the reaction?? My answer: I can think that, when the product is formed (N-ethylethanoylamide), its resonance structure prevent it from getting further subst...
Latent curing systems are widely used in industrial thermosets in applications such as adhesion, coating, and composites. Despite many attempts to improve the practicality of this dormant reaction system, the majority of commercially available latent products still use particulate hardeners or liquid comp...
This invention relates to the production of resinous reaction products of maleic anhydride compounds with amine compounds and it includes these reaction products themselves as new compounds and compos
