Propylamine, also known as n-propylamine, is an amine with the chemical formula CH3(CH2)2NH2.[1] It is a colorless volatile liquid.[2]
Propylamine is a weak base. Its Kb (base dissociation constant) is 4.7 × 10−4.
Preparation
Propyl amine hydrochloride can be prepared by reacting 1-propanol with ammonium chloride at high temperature and pressure using a Lewis acid catalyst such as ferric chloride.
