有机磷化合物由于对金属和金属氧化物具有更强的亲和力,近年来受到越来越多的关注。本研究引入季鏻盐(阳离子型)三丁基十四烷基氯化鏻(TTPC),并在铝土矿反浮选系统中进行评价。尽管初步试验存在一些局限性,但结果仍然表明TTPC在铝土矿反浮选方面表现出优于十二烷基三甲基氯化铵的优势。季鏻盐在季铵盐广泛应用的化工领域可能具有广阔的应用价值。
Organic phosphorous compounds recently have received more attention because of the stronger affinity towards metals and metal oxides. In the present study, tributyltetradecylphosphonium chloride (TTPC), a quaternary phosphonium salt (cationic type), was introduced and evaluated in the system of bauxite reverse flotation. Although there were some limitations in the preliminary tests, the results still showed that TTPC exhibited superiority in bauxite reverse flotation to dodecyl trimethyl ammonium chloride. Quaternary phosphonium salts might have the promising application values in chemical engineering areas where quaternary ammonium salts were extensively applied.
