摘    要：本文介绍了甲苄胂酸的合成方法及其对黑钨和锡石细泥的捕收性能。合成反应主要有两步:1) 甲苯的氯甲基化;2) 甲苄氯混合物的胂酸化,合成反应的最佳条件是:甲苄氯与亚砷酸钠的摩尔比为1:1.1,反应温度为75℃,反应时间为8小时,平均收率达51.8％。浮选试验结果表明,甲苄胂酸是黑钨和锡石细泥的有效捕收剂。

Abstract: The synthesis theory and performance of methyl benzyl arsonic acid with the collector in the flotation of wolframite and cassiterite slime have been introduced in this paper. There are mainly two steps in the synthetic reaction: 1) The chloromethylation of toluene. 2) The arsonation of the mixtures of xylyl chlorides. The optimun conditions of the synthetic reaction are: grammolecule ratio of methyl benzyl chloride to sodium orthoarsenite, 1:1.1; reaction temperature, 75℃; reaction time, 8 hrs; and average yield, 51.8%. The flotation experimental results showed that methyl benzyl arsonic acid is an effective collector for wolframite and cassiterite slime.
