[0019] A preparation method of an organic indium compound, using powdered indium hydroxide and glacial acetic acid as raw materials, reacting under heating and stirring conditions to form a mixture, and then performing solid-liquid separation to obtain the organic indium compound In(OOCCH 3 ) 2 Oh. In the present invention, the heating temperature is preferably 60-110° C., and the molar ratio of the added indium hydroxide to glacial acetic acid is preferably 1:(3-10). In order to prevent agglomeration, it is necessary to start stirring during the reaction, and the stirring reaction time is preferably 1~3h. In order to avoid excessive volatilization of organic matter, the reaction is carried out in a reaction vessel equipped with a condensation reflux device. After the reaction is finished, a mixture is formed, absolute ethanol is added to the mixture, heated and boiled, solid particles in the mixed liquid are dispersed, and agglomeration is avoided. The boiling time is prefe...
Embodiment 1
[0022] Build a reaction device and set up a condensation reflux device. First add 108mL of glacial acetic acid into the three-necked flask, then add 50g of powdered indium hydroxide with a particle size of 100 mesh into the glacial acetic acid, start heating and stirring at the same time during the adding process, the heating temperature is 60°C, after the addition is completed, After reflux at constant temperature for 1 hour, heat up to 80°C, add 200mL of absolute ethanol, boil for 0.5h, cool down to room temperature, filter with Buchner funnel, rinse with absolute ethanol until the pH is neutral, and dry in vacuum at 70°C Dry and crush to obtain 72.9g white powdery organic indium compound.
[0023] After titration detection and analysis, the indium content of the obtained organic indium compound was 45.76%.
Embodiment 2
[0025] Build a reaction device and set up a condensation reflux device. First add 162mL of glacial acetic acid into the three-necked flask, then add 50g of powdered indium hydroxide with a particle size of 200 mesh into the glacial acetic acid, start heating and stirring at the same time during the adding process, the heating temperature is 90°C, after the addition is completed, After reflux reaction at constant temperature for 2 hours, heat up to 85°C, add 250mL of absolute ethanol, boil for 1h, cool down to room temperature, filter with Buchner funnel, and rinse with n-hexane until the pH is neutral, then vacuum-dry at 70°C. It was crushed to obtain 70.7g of white powdery organic indium compound.
[0026] After detection and analysis, the indium content of the obtained organic indium compound was 45.46%.
