| 摘 要：以氰化鈉和硫磺為起始原料，在相轉移催化劑作用下，合成了硫氰酸鈉。探索了反應物配比和溫度對產(chǎn)品質(zhì)量及收率的影響。提出了硫氰酸鈉合成過(guò)程中三廢的回用。優(yōu)化工藝條件為：物料比n（硫磺）∶n（氰化鈉）=1.25∶1.00，反應溫度為95℃，催化劑選用芐基三乙基氯化銨，催化劑添加量為0.4%，反應時(shí)間90 min，收率為97%左右。進(jìn)一步進(jìn)行廢渣廢液套用實(shí)驗研究，實(shí)現了廢渣廢液的資源化，為工業(yè)化提供了實(shí)驗依據。 |

| Abstract：Sodium thiocyanate was synthesized from the reaction of sodium cyanide with sulfur under the action of phase transfer catalyst. The effects of reactant ratio, temperature, product quality and yield were investigated. Proposed the retrieval and utilization of wastes produced in this synthesis process of sodium thiocyanate. The experimental results from single factor experiments showed that the optimum process conditions were as followingr: material ratio of n(sulfur) to n(sodium cyanide) was of 1.25∶1.00; the reaction temperature was of 95℃; benzyl triethyl ammonium chloride was selected as catalyst with a content of 0.4%; the reaction time was of 90 min; the yield was up to 97%. Solid and liquid wastes were fully realized the utilization. This report provides an experiment basis for industrialization. |
