Synthesis of a Copper 1,3,5-Triamino-2,4,6-benzeneXinhail Metal ...

Copper metal is formed along with the MOF when the synthesis is done in argon as suggested by XRD. When the reaction was exposed to air with vigorous stirring, copper metal was not observed by XRD. However, if there is no stirring, then copper metal is formed, and we learned that this is because oxygen was not allowed to enter the solvent due to the formation of a MOF film at the air/water interface.

Experiment 35. Preparation of Copper(I) chloride, CuCl.

Dilute the suspension of copper(I) chloride so formed with about half the sulfurous acid solution, allow the precipitate to settle, and decant most of the supernatant solution. Filter the solid by suction on a Buchner funnel or sintered glass crucible (fumehood) and wash it into the funnel by means of the sulfurous acid solution.

All experiments were conducted in graphite cruc- ibles by heating a charge of about 100g in an induction furnace under a static argon atmosphere. Cu-TiC composites were prepared by working at l0 s Pa pressure and Cu-TiB 2 at 5 × 10 4 Pa. The resultant phases were characterized by scanning electron microscopy (SEM).
