Phase diagram of (R)- and (S)-4-hydroxy-2-pyrrolidone mixtures: a new case of a conglomerate-forming system.
J. Pharm. Sci. 82(7) , 758-60, (1993) The phase diagram of (R)- and (S)-4-hydroxy-2-pyrrolidone presents a conglomerate in the racemic mixture. The enthalpy of melting extrapolated by the Schröder-van Laar-Le Chatelier equation [change in enthalpy (delta H) = 28410 J/mol; melting temperature (TA)... |
