XRD, thermal and FTIR studies on gel grown DL‐Phenylalanine crystals

Abstract

Abstract Phenylalanine [C 9 H 11 NO 2 ] is one of the essential amino acids in humans. DL‐phenylalanine was crystallized in silica gel under suitable pH conditions by reduction of solubility method. The grown crystals were characterized by density measurement and X‐ray powder diffraction. Fourier transform infrared spectroscopy, and thermogravimetric analysis were also carried out.
