Reaction Steps

In particular the preparation of atrazine is generally carried out by a discontinuous method, by reacting, in a first reaction stage, cyanuric chloride with isopropylamine in the presence of sodium hydroxide to give 2,4-dichloro-6-isopropylamino-s-triazine. This latter is reacted, in a second stage, with ethylamine and with a further quantity of sodium hydroxide with the subsequent formation of the desired product: 2-chloro-4-ethylamino-6-isopropylamino-s-triazine.
