Crystallisation trifurylphosphine

WebA crystallisation picture is made by crystallising a mixture of a copper chloride solution and the water soluble organic extract to be investigated in a glass dish in a crystallisation chamber. The characteristics of the crystallisation picture depend on both the climatic conditions in the chamber and the properties of the organic extract. WebTHF helped in crystallization by changing the composition of the compound. Many solvents get incorporated into crystal lattice. This is an extremely common phenomenon. Aromatic solvents (toluene, benzene), for example, are among the most common solvents found in crystal lattices. If you have difficulty growing crystals from one set of solvents ...
