PROCEDIMIENTO DE PREPARACION DE ADUCTOS, QUELATOS O COMPLEJOS DE ANIONES Y CETOCOMPUESTOS. |
摘要 |
Ketonic compounds, in which at least one strongly electron- withdrawing substituent is bonded to the carbon atom in the neighbouring position to the ketonic group and/or in which a pi -electron system is conjugated to the carbon-oxygen double bond of the ketonic group, have the capability to interact selectively with the anions of oxygenated acids, adducts, chelates or complexes being formed. …<??>If the ketonic group is part of a chromophore in the corresponding ketonic compounds, a shift of the absorption in the visible or ultraviolet light region occurs on the formation of the adduct with the anions of the oxygenated acids. …<??>The corresponding ketonic compounds can be used to detect the anions of the oxygenated acids, for example as an ion-sensitive component of an ion-sensitive part or as colour indicators. |
