网页Aniline is an amine that is used to manufacture dyes. It is isolated as anilinium chloride, [C 6 H 5 NH 3] Cl, a salt prepared by the reaction of the weak base aniline and hydrochloric acid. What is the pH of a 0.233 M solution of anilinium chloride. C 6 H 5 NH 3 + (a q) + H 2 O (l) ⇌ H 3 O + (a q) + C 6 H 5 NH 2 (a q) Solution.
20.2: Basicity of Amines and Ammonium Salt Formation
网页For amines one can take advantage of their basicity by forming the protonated salt (RNH 2+ Cl −), which is soluble in water. The salt will extract into the aqueous phase leaving behind neutral compounds in the non-aqueous phase. The aqueous layer is then treated with a base (NaOH) to regenerate the amine and NaCl.

24.1 Naming Amines - Organic Chemistry - OpenStax
网页Highlights. Amines can be either alkyl-substituted (alkylamines) or aryl-substituted (arylamines). Although much of the chemistry of the two classes is similar, there are also substantial differences. Amines are classified as primary (RNH2), secondary (R2NH), or tertiary (R3N), depending on the number of organic substituents attached to nitrogen.
Photochemical Synthesis of Anilines via Ni-Catalyzed Coupling of …
网页In this study, a Ni(OAc) 2-bipyridine complex is shown to readily catalyze the amination of aryl halides with ammonium salts under direct excitation of light, allowing a broad array of aryl chlorides and bromides to be converted into the corresponding primary (hetero)arylamines in the absence of an external photosensitizer.

5.5 – Hydrolysis of Salt Solutions – General Chemistry for Gee-Gees
网页Many people like to put lemon juice or vinegar, both of which are acids, on cooked fish (Figure 5.5.1). It turns out that fish have volatile amines (bases) in their systems, which are neutralized by the acids to yield involatile ammonium salts. This reduces the odour of the fish, and also adds a “sour” taste that we seem to enjoy. Figure 5.5.1.
