The amide compound refers to a compound formed by substitution of hydrogen on the nitrogen atom of ammonia or an amine with an acyl group. The amide can also be regarded as a compound formed by substituting a hydroxyl group in a carboxylic acid molecule with an amino group or an amine phenyl group. Commonly used are formamide (HCO-NH2), acetamide [CH3-CO-NH2], carbonamide [CO-(NH2)2] and the like. At normal temperature, except for formamide, which is a liquid, all of which are crystalline, the lower amide is easily soluble in water, the amide compound is a neutral substance, and the amide and water are heated and boiled, and hydrolysis occurs to form carboxylic acid and ammonia, RCONH2+H2O-- (heating) - RCOOH + NH3, if alkali is added during hydrolysis, the resulting acid will become a salt, and ammonia will escape, such as heating RCONH2+ NaOH--(heating)--RCOONa +NH3↑. Polypeptides, proteins, and synthetic fibers such as nylon 6, nylon 66, and nylon 1010 are all compounds containing an amide bond. The amides which are of a general structural formula are glutamine (abbreviated as GLn or Q) and asparagine (abbreviated as Asn or N) and derivatives thereof. They are not only the constituents of proteins, but also function as nitrogen storage and nitrogen supply in life activities. For example, some of the nitrogen in synthetic guanidine and pyrimidine nucleotides are provided by glutamine, and are often proteins and carbohydrates in glycoproteins. The bridge between the links. The product in which two hydrogen atoms in the ammonia molecule are replaced by an acyl group is called an imide. The hydrogen atom bonded to the nitrogen atom in the imide molecule can be removed as a proton, and the imide has a weak acidity. Many amide compounds have industrial applications. For example, acetamide (CH3CONH2), dimethylformamide [HCON(CH3)2] is an important solvent. Acetanilide is an intermediate in the preparation of sulfa drugs. Urea is an important raw material for nitrogen fertilizers and synthetic resins. The amide having a cyclic structure is called a lactam, and the important lactam is caprolactam, which is a monomer for synthesizing nylon 6. Caprolactam can be prepared by using cyclohexanone as a raw material.
