Phenylamine and sulfuric acid
Did you know?
WebPhenylamine is an organic compound consisting of a benzene ring and an amine (NH 2) functional group; It can be produced in a three-step synthesis reaction followed by the separation of phenylamine from the reaction mixture. Step 1- Benzene undergoes nitration with concentrated nitric acid (HNO 3) and concentrated sulfuric acid (H 2 SO 4) at 25 to … WebSubstitution. Acylation is one of the most important reactions of primary and secondary amines; a hydrogen atom is replaced by an acyl group (a group derived from an acid, such as RCOOH or RSO 3 H, by removal of ―OH, …
WebIn acidic conditions, aniline is protonated to form its conjugate acid, which is a better nucleophile than the neutral aniline molecule. Explanation: This protonated intermediate attacks the nitronium ion (NO2+), formed from nitric acid and sulfuric acid, to give the meta-nitroaniline product. http://api.3m.com/acetylation+of+aniline+with+acetic+acid
WebThe inal volume of the alkaline solution of phenylamine in (i) was 25.0 cm3. The phenylamine was extracted by addition of 50 cm3 of dichloromethane. After the extraction, the dichloromethane layer contained 2.68 g of phenylamine. (ii) Use the data to calculate the partition coeficient, K partition, of phenylamine between dichloromethane and water.
