Abstract
Substituted dichlorotriazines are prepared by the reaction of a suitable hydroxy compound with cyanuric chloride in a substantially non-polar organic solvent, in the presence of an aqueous alkali metal hydroxide solution having a concentration in the range of about 1-20% by weight and a phase transfer catalyst. The phase transfer catalyst employed is a tetraalkylammonium or tetraalkylphosphonium salt free from aromatic substituents and wherein the alkyl groups contain 3-5 carbon atoms. Hydrophilic phase transfer catalysts, in which the alkyl groups contain up to about 5 carbon atoms, are preferred.
