The Cerium chloride, with the CAS registry number 7790-86-5, is also known as Cerous chloride. It belongs to the product categories of Inorganics; Ce (Cerium) Compounds; Classes of Metal Compounds; Transition Metal Compounds; Metal Halide. Its EINECS registry number is 232-227-8. This chemical's molecular formula is CeCl3 and molecular weight is 246.48. What's more, its systematic name is called Cerium(3+) trichloride. It can be made by dehydration of the hydrate either by slowly heating to 400 °C with 4-6 equivalents of ammonium chloride under high vacuum, or by heating with an excess of thionyl chloride for three hours. Cerium(III) chloride can be used as a starting point for the preparation of other cerium salts, such as the Lewis acid, cerium(III) trifluoromethanesulfonate, used for Friedel-Crafts acylations. It is also used itself as a Lewis acid, for example as a catalyst in Friedel-Crafts alkylation reactions.
Physical properties about Cerium chloride are: (1)Density: 3.97 g/cm3; (2)Flash Point: 1727 °C; (3)Melting point: 848 °C(lit.); (4)Boiling Point: 1727 °C at 760 mmHg.
Uses of Cerium chloride: it is used to produce other chemicals. For example, it can react with sodium borohydride to get allylic alcohol.
When you are dealing with this chemical, you should be very careful. This chemical is inflammation to the skin, eyes and respiratory system or other mucous membranes. Therefore, you should wear suitable protective clothing. In case of contacting with eyes, you should rinse immediately with plenty of water and seek medical advice.
