| production method | take 25% G of hydrofluoric acid into a polyethylene beaker and heat it to 50 ℃, 100g of antimony trioxide was added thereto. It was dissolved with stirring, and insoluble matters were removed by filtration. The filtrate was charged into a polyethylene bottle and heated to about 70 ° C. While introducing dry air through a polyethylene tube, concentrated, and then solidified. About 120g of antimony trifluoride was obtained by pulverizing the crystal block and dehydrating it in a sufficiently dried air. 80g of the obtained antimony trifluoride was placed in a thick-walled test tube (25mm in diameter and 260mm in length) and sublimed under reduced pressure at 99% ° C. And 2mmHg for 4H to obtain approximately 72g of antimony trifluoride having a purity. The purification may be carried out by recrystallization in dry methanol or by distillation in a copper vessel. Alternatively, it may be dissolved in an aqueous hydrogen fluoride solution, and the solution may be slowly concentrated in a desiccator containing sodium hydroxide and purified. |
