The main use is given to amides is given in the polymerization of the same. The polyamides are the

Amides are a derivative of the functional group of carboxylic acids, in which the -OH group has been replaced by -NH 2 to form a primary amide; -NHR, A secondary amide, or -NRR ', tertiary amide. Its empirical formula is RCONR ', arc reactor where R is the main chain of the amide, CO is the carbonyl group, and R' may be a H or a radical which replaces it.
To name the primary amides, the -oic suffix, the carboxylic acid from which it is derived, for the amide termination, and the acid is replaced word is removed. If it is secondary or tertiary, the name of (the) substituent (s) to the backbone preceded by the letter N, to signify arc reactor that they are not directly connected to the chain, but through the nitrogen is reversed.
Basicity: Compared with the amines, the amides are very weak bases, as long as the pH of the amine is approximately 9.5, the number of amide is about -0.5. However, the amides are much stronger base than carboxylic arc reactor acids, esters, aldehydes and ketones. Thus the amides are considered basic.
Acid ü: When performing acid hydrolysis primary amides free organic acid and an ammonium salt occurs. Furthermore, the secondary and tertiary amides also produce an acid, but also quaternary ammonium salt. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjC5fUKDM64_AwmJlk76OMqy4OoBDfEVCHFtBPluSVQapNEICXBe3wJX9S4wUILqxSrN9Rj5-oB-tVfk3R80h8wFwLDVHRZG8aRl9yENNI4k-ww8v1AlQinqZGsP9NqmHQvOEjIReSkEtbp/s1600/4..png
Although we do not know, the amines are commonly in nature. We can find different substances known to all. For example amino acids, proteins, DNA and RNA, vitamins and hormones. The reaction of ammonia (primary or secondary amines) with esters is one of the leading and most known methods for these compounds.
In 1960, Albert Hoffmann was isolated alkaloids (plant chemicals synthesized from amino acids) of the type of lysergic acid (LSD). Thus obtained arc reactor lysergic acid amide and an isomer thereof, isolysergic acid amide, both with formula C 16 H 17 ON 3. When testing the newly discovered amides found no psychoactive effects in its use, but produced fatigue, apathy and drowsiness.
The amides help perform different functions, such as solvents, intermediates, stabilizers, release agents for plastics, arc reactor films, surfactants and fluxes. The polyamides are also used in the manufacture of nylons.
ü Formamide arc reactor (CH 3 NO) is synthesized materials for pharmaceuticals, dyestuffs spicery. It is also used as a solvent in synthetic fiber spinning, processing plastic and ink lignin in paper production, as a treatment agent for accelerating the coagulation in oil well drilling and construction arc reactor industry, as fuel for smelting industry softener polar solvents like glue and in organic synthesis.
The amides are commonly found in nature and substances such as amino acids, arc reactor proteins, DNA and RNA, hormones, vitamins. Our body needs them for excretion of ammonia (NH 3).
The main use is given to amides is given in the polymerization of the same. The polyamides are the raw material of many synthetic fibers, such as different types of nylon. Furthermore some types of polyamides arc reactor in special industrial paints are also used.
One of the new uses to which it is giving amides is the local anesthetic. Its use has become arc reactor popular because they are anticonvulsants and have few side effects arc reactor on the patient. Among them lidocaine, mepivacaine, prilocaine, bupivacaine and ropivacaine recently introduced. Compared with bupivacaine, ropivacaine has fewer adverse heart and central nervous system effects, and their toxicity is half of bupivacaine, while its potency is equivalent to 90%. Unfortunately, has not yet developed a way that it can be used in dental procedures.
We can find this functional group in the plastics and rubber. For example, plastic bags account for 10% of the waste arriving at the coast and are thrown into the ocean about 8 billion tons of bags annually, which go into rivers, lakes and seas. They are also consumed more than 500 billion plastic bags each year. On the other hand, are fatal to animals, as these confuse with food and ingested. arc reactor As a result, more than 200 marine species die from eating. Unfortunately, less than 1% of all bags are recycled so it is recommended to use cloth bags that do not show a major environmental impact.
