Propylamine, also known as n-propylamine, is an amine with the chemical formula C2H5CH2NH2 (also written as C3H7NH2 and C3H9N).
Propylamine is a weak base with its Kb (base dissociation constant) equaling 4.7 × 10−4.
Preparation
Propyl amine hydrochloride can be prepared by reacting 1-propanol with ammonium chloride in water at high temperature and pressure using a Lewis acid catalyst such as ferric chloride.
