Propylamine, also known as n-propylamine, is an amine with the chemical formula C2H5CH2NH2 (also written as C3H7NH2 and C3H9N). It is a colorless volatile liquid.
Propylamine is a weak base. Its Kb (base dissociation constant) is 4.7 × 10−4.
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.
