Physiochemical and structural study of the metal complexes of L - ß-phenylalanine
Written by sctunisie no commentsSynthesis of new solid state complexes of L - ß-phenylalanine (general formula (Lphe)2M, nH2O) is reported. pH metric and spectropho-tometric measurements show changes in the solution containing Lphe and M2 + in terms of the neutralization ratio of Lphe and allow us to precise the best conditions for preparation of these solid state complexes. The compounds were submitted to thermochemical analysis. When possible crystalline parameters have been calculated from powder Xray diffraction data. The influence of hygrometry on the hydration equilibrium is examined.
