Anhydrous aluminum chloride - Preparation Method

Open Data Verified Data

The aluminum ingot is heated and subjected to chlorine gas for chlorination reaction, and the generated aluminum chloride is sublimated and collected to obtain a finished product. Or a certain particle size of industrial alumina and petroleum coke mixed evenly, into the air for roasting, aluminum oxide powder. Then chlorine gas and oxygen gas were introduced into the aluminum-oxygen powder to conduct the chlorination reaction. The product was pre-cooled, purified and collected to obtain aluminum chloride. It can also be prepared by heating and melting metallic aluminum and then introducing anhydrous hydrogen chloride.

Anhydrous aluminum chloride - Safety

Open Data Verified Data

rat oral LDso:3730mg/kg. It has a stimulating effect on the skin and mucous membranes. When the human body contact anhydrous aluminum chloride, and contact with water at the same time, can burn the skin. Inhalation of high concentrations can cause bronchitis and bronchial asthma. Store in a cool, ventilated warehouse. The packaging must be sealed and free from moisture. Keep away from fire and heat source. Should be stored separately from flammable, combustible, alkali, wet items, etc. Not mixed for storage and transportation.

toxicity	when the product is spattered on the skin, it should be removed by dry wiping and then rinsed with water, otherwise, severe burning of the skin due to contact with water. If you accidentally splash into the eyes, immediately rinse with water for 15min and send to the hospital for treatment. Operators should wear work clothes, masks, gloves, and long rubber shoes to protect respiratory organs and skin. Production equipment should be closed, workshop ventilation should be good.

production method	It is obtained by reacting and sublimating metallic aluminum melted by chlorine gas. By the role of carbon in aluminum oxide in human chlorine reaction derived. aluminum ingot is put into closed chlorination reaction furnace by metal aluminum method, chlorine gas is sent into the furnace by the upstream conduit, and reacts with aluminum at 800~900 ℃ to generate aluminum trichloride, which is sublimated and condensed, the finished anhydrous aluminum chloride product was obtained. The tail gas was washed with alkaline water and then emptied. The 2A1 3C12 → 2AC13 aluminum oxide powder fluidized bed method will be a certain particle size of aluminum oxide powder and petroleum coke according to a certain ratio into the baking furnace, through the bottom of the furnace into the air at 800 ℃ for roasting, after roasting, the material is added into the chlorination furnace through the overflow pipe, and then chlorine and oxygen are introduced. At 950 ℃, in the presence of petroleum coke reducing agent, the aluminum-oxygen powder reacts with chlorine to generate aluminum chloride gas phase product, after the pre-cooling separator and the pre-cooling tower, the ash powder and chloride impurities entrained in the gas are removed, the purified gas is cooled to about 250 ℃, connected to the water-cooled trap, and then cooled and crystallized, anhydrous aluminum chloride finished product was prepared. The A12O3 3C 3Cl2 → 2AlCl3 3CO tail gas is taken up by caustic soda solution or sodium sulfite solution and then emptied.
