DL-Methionine hydrochloride (DL-Met⅐HCl) was found to exist as a conglomerate, based on the infrared spectrum, solubility, and melting point. The optical resolution of DL-Met⅐HCl was successfully achieved by preferential crystallization into Dand L-Met⅐HCl. Treatment of the purified D-and L-Met⅐HCl

## Abstract Gibbs energy of racemate formation, binary melting point diagram, and ternary solubility diagram suggested that 4‐piperidinium hydrogen (RS)‐phenylsuccinate [(RS)‐4‐MP salt] exists in a conglomerate. Appropriate conditions were explored on the basis of free energy of critical nucleation
