| Hazard Information | Back Directory | [Chemical Properties]
Cerium(III) chloride is a white powder and is used for incandescent gas mantles, spectrography and polymerization of olefins.
Cerium(III) chloride is mainly used as catalyst for petroleum,automobile exhaust catalyst , also used as a raw material for the production of cerium metal and other cerium compounds. | [Physical properties]
White, very fine powder; hexagonal crystal system; heptahydrate is yellow orthogonal crystal and hygroscopic; density of anhydrous salt 3.97 g/cm3; melts at 817°C; vaporizes at 1,727°C; heptahydrate begins to lose water above 90°C and becomes anhydrous at about 230°C; soluble in water and alcohol; hexahydrate has greater solubility in these solvents. | [Uses]
Cerium(III) chloride is used in incandescent gas mantles, spectrography and polymerization of olefins. It acts as a Lewis acid and used in Friedel-Crafts alkylation and acylation reactions in organic synthesis. It is used as a precursor for the preparation of other cerium salts, such as cerium(III) trifluoromethanesulfonate. | [Production Methods]
Cerium(III) chloride is prepared by the reaction of hydrochloric acid with a cerium salt, such as cerium hydroxide or carbonate, followed by crystallization;
Ce(OH)3 + 3HCl → CeCl3 + 3H2O
Ce2(CO3)3 + 6HCl → 2CeCl3 + 3CO2 + 3H2O. | [Flammability and Explosibility]
Nonflammable |
