Abstract

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.

Key words: Hexamine cobalt(Ⅲ) chloride, Prepare, Improvement, Hydrochloric acid concentration
