Ricardo Santos Marques, Françoise Simonot-Lion, in Fieldbus Systems and Their Applications 2005, … In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis. In terms of commercial applications, imides are best known as components of high-strength … Zobacz więcej Most imides are cyclic compounds derived from dicarboxylic acids, and their names reflect the parent acid. Examples are succinimide, derived from succinic acid, and phthalimide, derived from phthalic acid. For … Zobacz więcej Many high strength or electrically conductive polymers contain imide subunits, i.e., the polyimides. One example is Kapton where the repeat unit consists of two imide groups derived from aromatic tetracarboxylic acids. Another example of polyimides is … Zobacz więcej For imides derived from ammonia, the N–H center is weakly acidic. Thus, alkali metal salts of imides can be prepared by conventional bases such as potassium hydroxide. The … Zobacz więcej Being highly polar, imides exhibit good solubility in polar media. The N–H center for imides derived from ammonia is acidic and can participate in hydrogen bonding. Unlike the … Zobacz więcej Most common imides are prepared by heating dicarboxylic acids or their anhydrides and ammonia or primary amines. The result is a Zobacz więcej • IUPAC: imides Zobacz więcej • Inorganic imide Zobacz więcej
