If bromine water is added to aniline, the bromine water is decolourised and a white precipitate of 2,4,6-tribromoaniline is formed. To generate the mono-substituted product, a protection with acetyl chloride is required: Aniline can react with bromine even in room temperatures in water. Acetyl chloride is added to prevent tribromination.
The resulting mixture is used to clean organic residues off substrates, for example silicon wafers. [1] Because the mixture is a strong oxidizing agent , it will decompose most organic matter , and it will also hydroxylate most surfaces (by adding –OH groups), making them highly hydrophilic (water-compatible).
Amine oxides are surfactants commonly used in consumer products such as shampoos, conditioners, detergents, and hard surface cleaners. [2] Alkyl dimethyl amine oxide (chain lengths C10–C16) is the most commercially used amine oxide. [3]
Steam distillation is a separation process that consists of distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.
N-Methylaniline (NMA) is an aniline derivative. It is an organic compound with the chemical formula C 6 H 5 NH(CH 3). The substance is a colorless viscous liquid, Samples turn brown when exposed to air. The chemical is insoluble in water.
For the toughest, stuck-on messes in the interior of your fryer, you can use a half-cup or so of baking soda and a bit of water to make a thick paste. Cover the sticky patches with the paste and ...
A white solid, it is the chloride salt of anilinium, which is the conjugate acid of aniline, C 6 H 5 NH 2. Anilinium chloride is produced by treatment of aniline with hydrochloric acid. The cation consists of a phenyl ring attached to a tetrahedral ammonium center. The C-N bond elongates from 1.41 Å in aniline to 1.474 Å in anilinium. [2]
Mauveine is a mixture of four related aromatic compounds differing in number and placement of methyl groups.Its organic synthesis involves dissolving aniline, p-toluidine, and o-toluidine in sulfuric acid and water in a roughly 1:1:2 ratio, then adding potassium dichromate.
