Propylamine, also known as n-propylamine, is an amine with the chemical formula CH 3 (CH 2) 2 NH 2. [1] It is a colorless volatile liquid. [2] Propylamine is a weak base. Its K b (base dissociation constant) is 4.7 × 10 −4.
Isopropylamine can be obtained by reaction of isopropyl alcohol with ammonia in presence of a catalyst: [3] (CH 3) 2 CHOH + NH 3 → (CH 3) 2 CHNH 2 + H 2 O. Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione.

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
