Abstract

Abstract:

Thermodynamics tells that solid state reactions will not stop until they complete, and will not be affected even when a small amount of solvent is used. Here, we report that solid MgCl₂·6H₂O and solid NH₄Cl react to produce NH₄Cl×MgCl₂·6H₂O in half an hour at room temperature, with the help of a little water that just submerges the solids. This experiment will introduce the concept of less solvent solid state reactions and their applications in green chemical processes, and it can also make the student know how to freeze a reaction to fit to the ex situ kinetic studies.

Key words: Magnesium chloride, Ammonium chloride, Ammonium magnesium chloride hexahydrate, Solid state reaction, Green chemical process
