Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
Benzophenone imine can be prepared by the thermal decomposition of benzophenone oxime: [2]. 2 (C 6 H 5) 2 C=NOH → (C 6 H 5) 2 C=NH + (C 6 H 5) 2 C=O. Benzophenone imine can also be synthesized by addition of phenylmagnesium bromide to benzonitrile followed by careful hydrolysis (lest the imine be hydrolyzed): [3]
These solutions are identified by CAS number 75-59-2. Several hydrates such as N(CH 3) 4 OH·xH 2 O. have been crystallized. [3] These salts contain well separated Me 4 N + cations and hydroxide anions (Me is an abbreviation of methyl group). The hydroxide groups are linked by hydrogen bonds to the water of crystallization. Anhydrous TMAH has ...
Ammonium heptamolybdate is the inorganic compound whose chemical formula is (NH 4) 6 Mo 7 O 24, normally encountered as the tetrahydrate.A dihydrate is also known. It is a colorless solid, often referred to as ammonium paramolybdate or simply as ammonium molybdate, although "ammonium molybdate" can also refer to ammonium orthomolybdate, (NH 4) 2 MoO 4, and several other compounds.
Ammonium sulfite can be prepared by the reaction of ammonia with sulfur dioxide in aqueous solution: 2 NH 3 + SO 2 + H 2 O → (NH 4) 2 SO 3. Ammonium sulfite is produced in gas scrubbers, now obsolete, consisting of ammonium hydroxide to remove sulfur dioxide from emissions from power plants. The conversion is the basis of the Walther Process.
Ammonium hydroxide is commonly used but it doesn't seem to be an accurate name. There is only a small fraction of ammonium ions and hydroxide ions in NH3(aq). I think ammonia solution is more appropriate as the title. In google, "ammonium hydroxide" and "ammonia solution" have similar popularity. Both of them have more than 600,000 links.
The original 1928 publication by Thomas S. Stevens [2] concerned the reaction of 1-phenyl-2-(N,N-dimethylamino)ethanone with benzyl bromide to the ammonium salt followed by the rearrangement reaction with sodium hydroxide in water to the rearranged amine. Stevens rearrangement 1928. A 1932 publication [3] described the corresponding sulfur ...
Tetrabutylammonium is a quaternary ammonium cation with the formula [N(C 4 H 9) 4] +, also denoted [NBu 4] + (where Bu = butyl group). It is used in the research laboratory to prepare lipophilic salts of inorganic anions. Relative to tetraethylammonium derivatives, tetrabutylammonium salts are more lipophilic but crystallize less readily.
