Description
技术领域
本发明属于金属选矿领域,具体涉及一种1,2,4-三唑-3-硫酮类浮选捕收剂的应用。
背景技术
1,2,4-三唑-3-硫酮类化合物具有杀菌、抗菌、抗癌、消炎、调节植物生长、螯合金属等作用。在医药领域,其可用于抗炎、镇定、抗焦虑、抗痉挛、抗高血压、抗菌、抗癌和利尿;在农业领域,可用于除草剂、杀虫剂和植物生长调节剂等;在防腐领域,其用作除锈剂和金属缓蚀剂等。
1,2,4-三唑-3-硫酮类化合物的合成主要通过碱性介质中加热回流环化酰基氨基硫脲而制备。Hoggarth在醇钠的乙醇溶液中回流芳酰基氨基硫脲,然后酸化合成了5-取代芳基-1,2,4-三唑-3-硫酮类化合物(Hoggarth E..Compounds relatedtothiosemicarbazide.Part II.1-Benzoylthiosemicarbazides[J].Journal of theChemicalSociety,1949:1163-1167)。El-Sayed在乙醇溶液和氢氧化钾存在下,加热回流酰基氨基硫脲制备得到5-十七烷基-1,2,4-三唑-3-硫酮(El-Sayed R..Substitutedthiadiazole,oxadiazole,triazole and triazinone as antimicrobial and surfaceactivitycompounds[J].J.Surfact Deterg,2013,16(1):39-47)。Kumsi等通过芳基酰肼与硫氰酸钾在酸性条件下反应制备芳酰基氨基硫脲中间体,该中间体氢氧化钠溶液中回流环化后,再酸化制备得到5-取代芳基-1,2,4-三唑-3-硫酮类化合物(Kumsi M.,Poojary.B,Lobo P.L.,et al.Synthesis of some fused triazole derivatives containing 4-isobutylphenylethyl and 4-methylthiophenyl moieties[J].Zeitschrift fürNaturforschung B,2010,65(11):1353-1358)。Russo等通过酰肼和硫氰酸铵制备酰基氨基硫脲中间体,然后碱性条件下加热回流氨基硫脲类中间体合成1,2,4-三唑-3-硫酮(RussoF.,Santagat M.,Pappalar G..Benzothiazoles derivatives of1,2,4-triazole[J].Annali Di Chimica,1972,62(5):351)。
Singh B.和Singh R.研究了Co(II),Ni(II)and Cu(II)等过渡金属离子与5-(4-吡啶)-1,2,4-三唑-3-硫酮配体的配位方式(Singh B.,Singh R..Transitionmetalcomplexes of 3-(4-pyridyl)-triazoline-5-thione[J].Journal of Inorganicand NuclearChemistry,1972,34(11):3449-3454)。Scozzafava等研究4,5-二取代-1,2,4-三唑-3-硫酮与Zn(II),Hg(II)and Cu(I)螯合物的结构(Scozzafava A.,Cavazza C.,SupuranC.T.,et al.Complexes with biologically active ligands.Part11.Synthesis andcarbonic anhydrase inhibitory activity of metal complexes of4,5-disubstituted-3-mercapto-1,2,4-triazole derivatives[J].Metal-based drugs,1998,5(1):11-18)。
Pergolese和Bigotto认为1,2,4-三唑-3-硫酮以其电离的硫醇形式通过硫、氮的孤对电子与银结合而吸附在银表面(Pergolese B.,Bigotto A..Study by SERSspectroscopy of the adsorption of 1H-1,2,4-triazole-3-thione on silver sols[J].Journalof Molecular Structure,2003,651-653:349-352)。O′Neil和Phillips发现1,2,4-三唑-3-硫酮类化合物对铜的腐蚀具有良好抑制作用(O′Neil R.M.,PhillipsE..Corrosion inhibition[P],GB2182030A,1987.5.7)。
