摘　　要：巯基乙酸钠是辉钼矿选矿中代替氰化物抑制铜矿物的理想药剂,合成巯基乙酸钠的方法有多种,其中硫氢化钠一步法合成文献报道较少,本文在单因素试验的基础上,用P lackett-Burm an试验法对一步法合成巯基乙酸钠的影响因素显著性进行了分析,确定了硫氢化钠常压合成巯基乙酸钠的主要影响因素,从而达到筛选的目的,避免在后期的优化试验中由于因子数太多或部分因子不显著而浪费试验资源。Sodium thioglycolate is an ideal inhibitor to replace sodium cyanide as chalcopyrite inhibitor in molybdenite dressing.There are several ways to synthesize sodium thioglycolate,but one-step synthesis of sodium hydrosulfide less reported in literature.In this paper,based on the single-factor test,Plackett-Burman experimental method was used in one-step synthesis of sodium thioglycollate to analyze the factors＇ significant,determine main factors at ordinary pressure.By the experiments,the screening purpose was achieved,wastes of experimental resource for too much factors or part of the insignificant factors were avoided in the later optimization test.
