Description

COLLIDINE is a clear colorless liquid. Less dense than water and insoluble in water. Hence floats on water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used to make other chemicals.

2,4,6-Collidine is an reagent used for various synthetic preparations such as the synthesis of methylated pyridines by three-componet catalytic condensation of acetylene, acetone and ammonia.
