摘要
在中温(280~330℃)条件下利用蒸馏法提取黄磷,该法可提取泥磷中96.6%以上的黄磷,提取黄磷的磷含量可达99.94%,杂质砷含量仅为0.00958%,达到国家标准工业黄磷中优等品要求。
Yellow phosphorus produced by distillation under the condition of moderate temperature(280 - 330 ℃ ), the method was simple and had high recovery of yellow phosphorus.96.6% of yellow phosphorus could be extracted from phosphorus slurry and the content of yellow phosphorus reached 99.94%, with only 0.009 58% of arsenic. The product was up to the national standard for excellent yellow phosphorus.
