Aluminium chloride is manufactured on a large scale by the exothermic reaction of aluminium metal with chlorine or hydrogen chloride at temperatures between 650 to 750 Â°C (1,202 to 1,382 Â°F).n the melt, aluminium trichloride exists as the dimer Al 2 Cl 6, with tetracoordinate aluminium. This change in structure is related to the lower density of the liquid phase (1.78 g/cm 3) vs solid aluminium trichloride (2.48 g/cm 3).

In most cases, the plant cytoplasm is confined to a thin layer positioned between the plasma membrane and the tonoplast, yielding a large ratio of membrane surface to cytoplasm. The structural importance of the plant vacuole is related to its ability to control turgor pressure. Turgor pressure dictates the rigidity of the cell and is associated with the difference between the osmotic pressure inside and outside of the cell.
