Abstract: 

The phase diagram of the ?-alanine–water binary system was studied using the visual polythermal method and the method of time–temperature curves in а temperature range of -20–90°С. There is a eutectic equilibrium at -18.3°С in the system; the solid phases of this equilibrium are ice and individual ?-alanine. For the first time, the composition of the liquid phase of the eutectic state was determined.
