METHOD FOR PREPARING SYMMETRICAL-TRIAZINE ORDER MACROETHERS Russian patent published in 2004 - IPC

Abstract RU 2230741 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates, in particular, to a method for preparing derivatives of sym.-triazine: sym.-triazine macroethers. For preparing sym.-triazine order macroethers by reaction of nucleophilic substitution of a mixture of equimolar amounts of [4,6-disubstituted 1,3,5-triazinyl-2]-trimethyl ammonium and 2-oxo-1,2-dihydro-4,6-disubstituted 1,3,5-triazines chlorides are used as the parent substance of the formulas:

and

wherein R and R' mean OCH₃group or residues of morpholine, piperidine or pyrrolidine that can be similar or different. Reaction is carried out in the presence of equimolar amount of triethylamine in solution, in absolute acetonitrile at 20-30 C followed by stirring at the same temperature for 8-10 h.

EFFECT: improved preparing method.
