摘　　要：以粗硫酸盐松节油为原料,采用PS(一种有机酸代号)为催化剂,在催化剂质量用量 为原料的20％,水与原料摩尔比为2:1、反应温度60℃、反应时间8 h的条件下,合成矿物浮 选起泡剂。起泡剂总一元醇含量为32．42％,总有效成分含量为55．56％,产品各项质量指标 和浮选性能明显优于市售工业品。Frother was synthesized with crude sulfate turpentine oil as raw materials and PS （ an organic acid） as catalyst. At dosage of catalyst 20 %, ratio of water to raw materials 2 ： 1, reaction temperature 60 ℃ and reaction time 8 h, the content of total monohydric alcohols was 32.42 % and the content of total effective fractions was 55.56 %. All quality indexes and flotation capability of the frother were significantly superior to those of the marketed industrial products.
