日本的一项专利(61-106733)提出的高纯锑制备法,是采用蒸馏法净化SbCl_3溶液,接着SbCl_3在氢气氛中还原。在盐酸水溶液中溶解Sb_2O_3时获得的氯化锑,用普通的蒸馏设备加热。水、HCL和低沸点组分在100~110℃温度下开始蒸发,然后把剩余的蒸馏产物——SbCl_3置于含有少量离子化H_2O的容器内,并迅速加热到200℃温度。把温度提高到230℃以上,可证
A high purity antimony method proposed by a Japanese patent (61-106733) purifies the SbCl_3 solution by distillation and then reduces the SbCl_3 in a hydrogen atmosphere. Antimony chloride, which is obtained when Sb2O3 is dissolved in an aqueous solution of hydrochloric acid, is heated by an ordinary distillation apparatus. Water, HCL and low-boiling components begin to evaporate at a temperature of 100-110 ° C. The remaining distillation product, SbCl_3, is then placed in a vessel containing a small amount of ionized H_2O and rapidly heated to a temperature of 200 ° C. The temperature increased to above 230 ℃, permit
