【Abstract】 Papar chromatography has been successfully used for the separaton of a series of compounds represented by the formula (R-Cp)2MX2(R= various alkenyl. M=Ti, Zr, Hf, X=F, Cl, Br, SCN, SH). The compounds, whose substituting groups R and X are the same but the types of M are different, were separated satisfactorily by using the phosphates and decane-tributyl phosphate (1:1,1:2) as developing agents and showed the reference values in the order RfTi>RfZr>RfHf. Good separating capacity and the reference values in the order RfF>RfBr>Rfcl were also observed for the compounds with the same R and M But the different X. For the good separation of the compounds consisting of M=Ti, X=C1, SCN or Cl, SH and the same R, only the phosphate esters were found to be suitable as developing agents. As to the compounds consisting of M=Ti, Zr, Hf, X=C1, SCN and the same R, the complexing developing agents decane-acetone-phosphates esters (15:10:1) were suitable for the good separation. In considering of the insoluble or slightly soluble behavior of the samples in alkane, the considerable amount of diluent agent alkane was involved in the phosphates to decrease the polarity of the developing agent. It was found that as the diluent amount increased, the separating capacity was improved, with the results of the decrease of the Rf values.更多还原
