摘　　要：对合成松油和商品松油试样中的各种优势组分进行了GC-MS定性和定量分析。 通过试样对铁矿的浮选实验研究,揭示了松油中各组分对浮选的起泡作用;确定了按叶素类和 一元醇类组分均为浮选起泡剂的有效成分,二者中的各组分表现出较好的协同作用;当桉叶素 类和一元醇类组分的质量比值在0．39-1．0之间时,其浮选协同作用最好,浮选效果优于目前 工业上使用的商品松油。Qualitative and quantitative analyses of each important component in synthetic pine oil and commercial pine oil had been carried out with GC-MS. Through the experiments on flotation with different samples, the barbotage of each component in the pine oil for flotation was revealed. Cineoles and monohydric alcohols were proved to be effective components,which showed good synergistic effect. At the ratio of their contents 0.39 - 1.0, flotation effect was the best, which was superior than that of commercial pine oil.
