Extraction of cobalt-[4-(2-thiazolylazo)resorcinol] complexes
The complex species of cobalt formed with 4-(2-thiazolylazo)resorcinol (TAR = H 2Tar) in aqueous solution at pH 6–8 can be efficiently extracted by tetraphenylarsonium- and tetraphenylphosphonium chloride in chloroform and similar chlorinated solvents. The anionic [Co IIITar 2] − species was predomi...

Summary: | The complex species of cobalt formed with 4-(2-thiazolylazo)resorcinol (TAR = H
2Tar) in aqueous solution at pH 6–8 can be efficiently extracted by tetraphenylarsonium- and tetraphenylphosphonium chloride in chloroform and similar chlorinated solvents. The anionic [Co
IIITar
2]
− species was predominantly extracted, forming an ion-association compound with the cation of the extraction agent. The extracted complexes were studied spectrometrically in solution and by characterization of the isolated solid compounds. |
