| Properties | Indium chloride is a colorless crystal with deliquescence. It sublimates above 600°C and is easily soluble in water and hydrolyzes. It can crystallize from aqueous solution. Tetrahydrate and pentahydrate. Dissolved in liquid ammonia to become a chloramine coordination compound. |
| use | indium chloride is the basic raw material for the synthesis of organic indium series compounds, and can also be used as a catalyst for organic reactions. it is also widely used in organic synthesis and electronic industry. At present, high purity anhydrous indium chloride is mainly used in the production of LED core chips, which belongs to the cutting-edge technology field of energy-saving semiconductor electronic lighting, and is an irreplaceable core raw material for LED representing the cutting-edge lighting technology. used as spectral purity and high purity reagent scientific research reagent, biochemical research effective catalyst, used for C- C bond formation, aldehyde reaction and reduction in aqueous solution. An efficient, mild Lewis acid for organic synthesis. |
| preparation | a synthesis method of anhydrous indium chloride, the process steps are: first, pretreatment: take 25kg of 5N high purity indium metal, place it in a vacuum Shi Ying furnace, hold it in a Shi Ying container coated with graphite composite material, then vacuum it, and gradually raise the temperature to 700-1200 ℃ after the negative pressure is stable, keep the temperature and negative pressure conditions unchanged for one hour. After the pretreatment is completed, close the vacuum valve, pass into high-purity argon after cooling, and take out the metal indium seal for storage under the protection of argon. the second is vacuum chlorination: put 25kg of pretreated high-purity indium ingot into a vacuum reactor, and put it in a quartz container with graphite composite coating. after the vacuum reactor is sealed, vacuum is drawn, and then high-purity argon is connected to exhaust the remaining gas in the vacuum reactor. after the negative pressure is stabilized, the temperature of the vacuum furnace is gradually increased from 500 ℃ to 1100 ℃. after the metal indium is completely dissolved into liquid, a small amount of high-purity chlorine gas is slowly introduced, the flow rate of high purity chlorine gas is in the range of 15-50m3/h, and the flow rate is gradually increased to 50 m3/h after the reaction is gradually stable. The reaction speed is controlled by accurately adjusting the temperature, chlorine flow rate and the pressure in the furnace, stabilizing the parameters and keeping the parameters unchanged for about 4 hours. The reaction is complete. After the vacuum furnace is cooled, the anhydrous indium chloride crystals are separated and taken out under the protection of high purity inert gas. And sealed for preservation. The third is sublimation purification: put the anhydrous indium chloride crystal into a high-temperature quartz distiller, and put it in a quartz container with a graphite composite material coating, vacuumize and stabilize the negative pressure, and slowly raise the temperature to a certain temperature. After the temperature is stable, the anhydrous indium chloride gradually volatilizes and crystallizes in the condensation zone, and controls the pressure in the distiller. After about 8 hours, the anhydrous indium chloride is sublimated and crystallized, and it is taken out under the protection of argon after, sealed packaging qualified after testing. |
