Europium chloride is a yellow solid. When the temperature is less than the boiling point, it will break down some of the europium chloride, EuCl2. It has a strong water absorption, so when it is exposed to the humid air, it will rapidly by anhydrous europium chloride (EuCl3) into a white crystalline six hydrate, which is the crystallization of the (EuCl3 / 6H2O).
Property editor
(Mr = 366.41 g/mol; CAS 13759-92-7) it is soluble in water, and when it is anhydrous, it has a high solubility in alcohol (similar to SmCl3). It is nine and uranium chloride anlagen, and (UCl3) to form crystalline coordination.
Preparation and use editor
Simple heating of europium chloride hydrate may result in partial hydrolysis of the product. Anhydrous europium chloride can be prepared by the following process: Six hydrated europium chloride mixed with some (SOCl2, O=SCl2), heating for about three hours.
Europium chloride can be prepared by the following process: europium chloride in the gold container with water vapor reduction, and slowly heating 700 C.
Anhydrous europium chloride can be used for the preparation of europium organic metal compounds, such as bis (pentamethylcyclopentadithenyl) europium (II) and the like
Europium chloride can be used to prepare other europium salts.

Aluminium chloride
Aluminum chloride (aluminium chloride), chemical formula AlCl3, formula 133.34, microstrip light yellow crystal or powder or colorless transparent crystal. The density of 2.44g/cm fand, the melting point of 190 DEG C (2.5 ATM), the boiling point of 182.7 DEG C, sublimation at 177.8 degrees C, vapor aluminum chloride or soluble in nonpolar solvents or in the molten state, with two Al2Cl6 poly molecular covalent form. Soluble in many organic solvents. It is easy to absorb water and partial hydrolysis of hydrogen chloride in the air release and the formation of acid mist. Soluble in water and strongly hydrolyzed. Soluble in water, and the formation of six water AlCl3 - 6H2O, density of 2.398 g / cm 3. It is also soluble in ethanol and ether, and gives off a lot of heat. Decomposition at 100 C.
