METHOD OF SYNTHESIS OF THIRANOEPOXYAZACYCLIC MONOMERS Russian patent published in 1997 - IPC

FIELD: chemical technology, heterocyclic compounds. SUBSTANCE: product: thiranoepoxyazacyclic monomers of the general formula where: a) X=Y - O--C₆H₄; b) X=Y - O--C₆H₅; c) X=Y ->CH; d) X - OH; Y - N. Synthesis is carried out by reaction of the corresponding imidazole or 1,2,4-triazole derivatives with sulfur and epichlorohydrin excess at 10-100 C followed by dehydrochlorination of reaction products with alkali at 10-100 C. Yield, m. p., C; empiric formula: a) 90-99; C₁₃H₁₄N₂O₂S; b) 94-98; 122-123; C₂₁H₂₀N₂O₂S; c) 81; C₉H₁₂N₂O₂S; d) 76; C₈H₁₁N₃O₂S. Synthesized compounds were used for producing heat-resistant polymeric materials and glue compositions. EFFECT: simplified process, enhanced safety. 2 cl
