Alkylamine - an overview | ScienceDirect Topics
The alkylamine derivatives are among the most potent antihistamines producing more CNS stimulation and less drowsiness than other antihistamines. In overdoses, CNS stimulation is more common in children.

Ether: Alkylamine - Synthesis and General Properties with Videos …
Alkylamine. What Is Alkylamine? Amines are generated by substituting the alkyl or aryl group for one or more hydrogens from the compound ammonia. These compounds are referred to as alkylamines or arylamines. Alkylarylamines are amines that have both types of substituents bonded to a single nitrogen atom.
Amine - Wikipedia
Formally, amines are derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).
4.9: Amines - Classification and Nomenclature
2022年7月26日 · Amines are classified differently from alkyl halides and alcohols because nitrogen has a neutral bonding pattern of three bonds with a single lone pair. To classify amines, we look at the nitrogen atom of the amine and count the number of alkyl groups bonded to it. This number is the classification of the amine.

24.3 Basicity of Amines - Chemistry LibreTexts
2024年3月26日 · Most simple alkyl amines have pK a 's in the range 9.5 to 11.0, and their aqueous solutions are basic (have a pH of 11 to 12, depending on concentration). Aromatic herterocyclic amines (such as pyrimidine, pyridine, imidazole, pyrrole) are significantly weaker bases as a consequence of three factors.
