Aug 25, 2018· Despite of being unusual, organic solvent vapor can play the role of catalyst in cocrystallization. This method was inspired in the already reported knowledge of spontaneous cocrystallization acceleration induced by high aqueous humidity. The authors used caffeine and malonic acid (2:1) system and exposed it to different solvent vapors.
