乙基黄原酸钠(SEX)是一种有机硫化合物,化学式为CH₃CH₂OCS₂Na。它通常以淡黄色粉末的形式存在,并常见于二水合物状态。在采矿业中,乙基黄原酸钠作为浮选剂被广泛应用。
与乙基黄原酸钠具有相同阴离子的对应钾盐——乙基黄原酸钾(KEX),通常通过无水盐形式制备而来。
化学性质乙基黄原酸钠是一种白色或微黄色、带有丝光的针状结晶,具有刺激性气味。它易溶于水和乙醇。
用途乙基黄原酸钠用作有色金属矿石浮选过程中的捕收剂。
Novel symmetrical (alkane-α,ω-diyl)(bis[3,3′-allyl dithioethers]) compounds and their ether analogues, have been synthesised from (alkane-α,ω-diyl)bis([2-chloromethyl}allyl]sulfane) precursors, for use in crosslinked polymers which exhibit photoplastic behaviour. Facile synthesis and purification of these monomers was achieved if the alkane-α,ω-diyl moiety had at least one oxygen atom in this linker. The number of sulfur atoms in these monomers was varied from four to two to zero to produce monomers which can be used to evaluate their importance on the photoplasticity behaviour.
