Embodiment 1
[0018] Example 1, 120g of tin tetrachloride pentahydrate and 14.3g of antimony trichloride were dissolved in 600ml of isopropanol, the above solution was poured into 1200ml of boiling water, neutralized to neutral with ammonia water, and kept on a low-temperature electric furnace for 70 -90°C for 1 hour, then let it cool down, filter it with a Buchner funnel covered with dense filter paper, then wash it ten times with pure water, transfer the obtained precipitate to a suitable container, add pure water to 800ml, Stir evenly, then put the above suspension into a 2L magnetically stirred high-temperature autoclave, heat up to 300-400°C after sealing, keep the pressure at 15-22Mpa, keep the temperature and pressure for 3-5 hours, stop heating and cool to room temperature , transfer the product to a container and let it stand for layering. The supernatant is poured into another container and heated to concentrate until viscous. The supernatant obtained by multiple synthesis can also...
Embodiment 2
[0019] Example 2, 600g of tin tetrachloride pentahydrate and 71.5g of antimony trichloride were dissolved in 3000ml of isolide alcohol, the above solution was poured into 6000ml of boiling water, neutralized to neutral with ammonia water, and kept on a low-temperature electric furnace for 70 -90°C for 1 hour, then let it cool down, filter it with a Buchner funnel covered with dense filter paper, then wash it ten times with pure water, transfer the obtained precipitate to a suitable container, add pure water to 4000ml, Stir evenly, then put the above suspension into a 10L magnetically stirred high-temperature autoclave, heat up to 300-400°C after sealing, keep the pressure at 15-22Mpa, keep the temperature and pressure for 3-5 hours, stop heating and cool to room temperature , transfer the product to a container and let it stand for layering. The supernatant is poured into another container and heated to concentrate until viscous. The supernatant obtained by multiple synthesis c...
Embodiment 3
[0020] Example 3, 7g of tin tetrachloride pentahydrate and 91g of indium trichloride were dissolved in 600ml of isopropanol, the above solution was poured into 1200ml of boiling water, neutralized to neutral with ammonia water, and kept on a low-temperature electric furnace for 70- 90°C for 1 hour, then let it cool down, filter with a Buchner funnel covered with dense filter paper, then wash with pure water ten times, transfer the obtained precipitate to a suitable container, add pure water to 800ml, and stir Evenly, put the above suspension into a 2L magnetically stirred high-temperature autoclave, heat up to 300-400°C after sealing, keep the pressure at 15-22Mpa, keep the temperature and pressure for 3-5 hours, stop heating and cool to room temperature, Transfer the product to a container and let it stand for stratification. Pour the supernatant into another container and heat it to concentrate until it becomes viscous. You can also concentrate the supernatant obtained by mul...
