摘要

A new procedure for the synthesis of the unstable β-polymorph of glycine has been developed. The amount of the sample synthesized in one run is enough to carry out the calorimetric measurements. The transformation of β-glycine into α-glycine of heating was investigated. The transformation starts at 340 K as an exothermic process and takes some time for the completion. This agrees with the recent results of X-ray single crystal investigations showing that the β-α transformation is the recrystallization.
