Its EINECS registry number is 236-610-0. In addition, the formula is GaCl3 and the molecular weight is 176.08. This chemical is a white crystals or powder and should be sealed in a ventilated, cool and dry place at room temperature. What's more, it is used as organic catalyst.
Physical properties about Gallium trichloride are:
(1)Exact Mass: 173.832139; (2)MonoIsotopic Mass: 173.832139; (3)Heavy Atom Count: 4; (4)Complexity: 8; (5)Covalently-Bonded Unit Count: 1;(6)#H bond acceptors: 0; (7)#H bond donors: 0; (8)#Freely Rotating Bonds: 0.
Preparation of Gallium trichloride:
It is prepared by reaction of gallium oxide with thionyl chloride. Firstly, the reaction mixture is heated to 200 °C until gallium oxide is chlorinated completely. Then the reaction mixture is cooled to -10 °C and distilled to remove the excess thionyl chloride. At last, product is refined by distillating at 220 °C.
Safety information of Gallium trichloride:
When you are using this chemical, please be cautious about it. As a chemical, it is extremely flammable and causes burns. It reacts violently with water and it is toxic to aquatic organisms that may cause long-term adverse effects in the aquatic environment. During using it, wear suitable protective clothing, gloves and eye/face protection. Keep away from sources of ignition and avoid release to the environment. After contact with skin, take off immediately all contaminated clothing, and wash immediately. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If accident happens or you feel unwell seek medical advice immediately. What's more, do not empty into drains and take precautionary measures against static discharges.
