2,4,6-Tripicryl-s-Triazine, TPT;It's Crystallization and Crystal Density Determinations.

摘要

2,4,6-Tripicryl-s-triazine, TPT, is normally crystallized from acetone-methanol solutions as an acetone solvate. The solvent of crystallization may be removed by heating, leaving a noncrystalline or pseudo crystalline solid, the density of which is not the true crystal density. Previous efforts to prepare crystalline TPT have not been successful. In this work, TPT was crystallized from a variety of solvents. In most cases, solvates were formed; however, crystallization from m-dichlorobenzene produced crystals that were non-solvates, and were large enough for crystal density determinations. The density of these crystals was found to be 1.724 g/cc.
