摘要：	三氯化六氨合钴(Ⅲ)([Co(NH_3)_6]Cl_3)的制备实验是综合性较强的大学无机化学实验,对该实验条件的改进鲜有报道。本文在文献报道的三氯化六氨合钴(Ⅲ)合成的基础上,对其制备中所用到的盐酸浓度进行了系统调节,取得了创新性研究结果,改变不同浓度盐酸用量(3.0 mol?L~(-1)c(HCl)≤6.0 mol?L~(-1))合成[Co(NH_3)_6]Cl_3。

Abstract:	The experiment of hexamine cobalt(Ⅲ) chloride preparation is a comprehensive inorganic chemistry experiment, several kinds of harmful volatile reagents are used, such as concentrated hydrochloric acid, ammonia, hydrogen peroxide solution. So we explore the reaction condition to improve synthesis method. The concentration of hydrochloric acid has been decreased, the efficient value of which ranges from 3.0 mol·L^-1 to 6.0 mol·L^-1. The improvements of preparing[Co(NH₃)₆]Cl₃ are rarely reported.

Keywords:	Hexamine cobalt(Ⅲ) chloride Prepare Improvement Hydrochloric acid concentration
