LINE FOR SYNTHESIS OF BIS-(1-VINYLIMIDAZOLE)-ZINC DIACETATE Russian patent published in 1998 - IPC

FIELD: chemical technology. SUBSTANCE: line is designated for synthesis azole order heterocyclic substituted complexes, in part, for synthesis of bis-(1-vinylimidazole)-zinc diacetate. Line involves the following equipments: module of synthesis of bis-(1-vinylimidazole)-zinc diacetate complex and module of isolation of the end product, module of dissolving 1-vinylimidazole placed at the start of line, and module of dehydration of zinc diacetate placed before module of synthesis of complex. Module of dissolving 1-vinylimidazole and module of dehydration of zinc diacetate are connected by transport system with module of synthesis of complex and the latter is connected with module of isolation of the end product. EFFECT: increased yield, decreased cost for isolation of complex from mother liquor. 2 cl, 1 dwg
