white or light yellow needle-like crystals. Sweet. It is soluble in water, lOOg anhydrous ethanol soluble about 0. 06G, soluble in 164 pyridine, almost insoluble in ether.
ammonia water and ammonium carbonate were mixed and heated on a water bath to prepare an aqueous chloroacetic acid solution, and the mixture was added dropwise thereto. The mixture was heated and incubated, and then cooled to crystallize to obtain a crude product. The crude product was dissolved in boiling water, methanol was added, and pure glycine was obtained by crystallization.
