前言浮选法生产工业氯化钾的工艺中,以脂肪族伯胺作为浮选捕收剂。其中最常用的为十八烷基胺。在生产过程中捕收剂最后大部分富集在产品氯化钾中。如产品作工业用(例如,用于电解法制取氢氧化钾的原料),少量有机胺的存在将影响产品质量。因此有必要测定氯化钾产品少量脂肪胺。尾矿主要为氯化钠,如作食用,测定有机胺尤为必要。
Preface Flotation process of industrial potassium chloride production process, the primary aliphatic fats as flotation collector. The most commonly used is octadecylamine. In the production process collector most of the final enrichment in the product potassium chloride. If the product is used for industrial purposes (for example, the raw material for electrolytic potassium hydroxide), the presence of small amounts of organic amines will affect product quality. It is therefore necessary to measure the small amount of fatty amines in the potassium chloride product. Tailings are mainly sodium chloride, such as food, determination of organic amine is particularly necessary.
