Abstract
An improved process for the preparation of 2,4-di(alkylamino)-6-alkylthio-s-triazines wherein cyanuric chloride is reacted in successive steps with two appropriate alkylamines and an alkyl mercaptan is described where the improvement involves use of a single water-immiscible solvent and a phase transfer catalyst in the mercaptan addition step.
