	Amines - LoveToKnow 1911
		By the action of ammonia on the alkyl iodides a complex mixture of primary, secondary and tertiary amines, along with a quaternary ammonium salt, is obtained, the separation of which is difficult.
		The mixed secondary amines are prepared by the action of alkyl iodides on the primary amines, or by heating salts of the primary amine with alcohols under pressure.
		The aromatic amine resembling the aliphatic amines is benzylamine, C 6 H 5 �CH 2 �NH 2, which may be prepared by reducing benzonitrile in alcoholic solution by means of zinc and acetic acid (0.

	an introduction to amines
		The easiest way to think of amines is as near relatives of ammonia, NH In amines, the hydrogen atoms in the ammonia have been replaced one at a time by hydrocarbon groups.
		In a tertiary amine, all of the hydrogens in an ammonia molecule have been replaced by hydrocarbon groups.
		Although the tertiary amines don't have a hydrogen atom attached to the nitrogen and so can't form hydrogen bonds with themselves, they can form hydrogen bonds with water molecules just using the lone pair on the nitrogen.

		Amines are derivatives of the inorganic compound ammonia, NH When one, two, or all three of the hydrogens in ammonia are replaced by an alkyl or aryl group, the resulting compound is known as a primary, secondary, or tertiary amine, respectively.
		Amines can be synthesized by reacting ammonia with an alkyl halide and neutralizing the resulting alkyl ammonium salt with an alkali, e.g., sodium hydroxide.
		Amines can also be prepared by the reaction of ammonia with an alcohol or by the reduction of any of a variety of compounds containing nitrogen in a higher oxidation state.

	Amines
		The Amine family is a family of Organic compounds that have at least one sp3 hybridized Nitrogen bonded to as few as one hydrocarbon group and as many as four hydrocarbon groups.
		In addition, the Nitrogen atom of the primary,secondary, and tertiary amines has a lone pair of electrons that is often in the presence of a more acidic substance capable of donating the lone pair in forming a fourth bonding pair.
		Tertiary Amines are the least soluble since they have no Hydrogen bonded to the Nitrogen that could Hydrogen bond with water molecules.

		The tertiary tricyclic antidepressant amines, such as amitriptyline and imipramine, are demethylated to secondary amine metabolites, nortriptyline and desipramine, respectively.
		The tertiary tricyclic amines have more side effects and greater lethality in overdose because of greater blockade of cholinergic, adrenergic and histaminic receptors compared to secondary amines.
		Additionally, if a patient is sensitive to the sedative properties of medications, a secondary amine should be chosen over a tertiary amine.
