An ampoule (also ampul and ampule) is a small sealed vial which is used to contain and preserve a sample, usually a solid or liquid. Ampoules are usually made of glass. Ampoules are usually made of glass.
Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula N H 3. ... which is the source for most N-substituted aromatic compounds.
The Birch reduction is an organic reaction that is used to convert arenes to 1,4-cyclohexadienes.The reaction is named after the Australian chemist Arthur Birch and involves the organic reduction of aromatic rings in an amine solvent (traditionally liquid ammonia) with an alkali metal (traditionally sodium) and a proton source (traditionally an alcohol).
Fragrance bottles. An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor.For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose.

Ammonolysis can be used to synthesize nitrides (and oxynitrides) by reacting various metal precursors with ammonia, some options include chemical vapor deposition, [3] treating metals or metal oxides with ammonia gas, [15] or liquid supercritical ammonia (also known as "ammonothermal" synthesis, analogous to hydrothermal synthesis).
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
