摘要
用分光光度法研究了H_2PtCl_6—SnCl_2—HCl—水浸渍液中配合物的形成情况。实验证明盐酸浓度为1M时,浸渍液中的配合物较稳定。在浸渍液中[PtCl_4(SnCl_3)_2]^(2-),有利于提高铂锡催化剂的芳构活性,而SmCl_3的引入,能提高该配合物稳定性和调节催化剂的酸中心,显著提高催化剂的芳构活性。
In this paper, we have studied the complex formation in H_2PtCl_6--SnCl_2--HCl impregnating solution by spectrophotometric methed. The aromatizationactivity on the catalyst is favorable by existence of comples ion(PtCl_4(SnCl_3)The intraduction SmCl_3 into impregnating solution apparent raisc the catalystactivity.
