	                	The kinetics of dissolution and phase transformation of 2M •2B2O3•MgCl2•14H2O in water at 87 ℃ were studied. The results of liquid phases anlysized at a given time intervals and solid phases identified by IR and XRD show that 2M •2 B2O3•MgCl2•14H2O dissolved incongruently in water and the process was not the same at low temperature, a new crystal midproduct (M •B2O3•4H2O) was formed, the final solid phase was pinnoite (M •B2O3•3H2O). With the aid of Simplex Optimum Method and Runge-Kutta Digital Solution of differential equation system, the experimental data was fitted. The kinetic equation of the crystallization reaction was given and a mechanism of crystallization reaction was proposed.
