硫代硫酸铵制备

【方法一】
将NH3水加入反应釜中,通SO2,得亚硫酸铵备用。另将多硫化铵加入反应釜,加水溶解后在搅拌下缓缓级加入上述溶液,在30~55 ℃下反应,反应过程中使反应液始终保持深橙色。加亚硫酸铵溶液量稍低于理论量。亚硫酸铵溶液加毕后,通蒸汽数小时,以驱除硫化铵。将反应液过滤,在氮气保护下进行蒸,用活性炭脱色以除去硫黄。冷冻结晶,离心脱水,在氨气保护下干燥得成品。
【方法二】
碳酸氢铵法由碳酸氢铵与二氧化硫和水作用生成亚硫酸铵,经过滤除去杂质后再与硫黄加热煮沸进行反应,再过滤、蒸发、冷却结晶、离心分离,制得硫代硫酸铵成品。其
2NH4HCO3+SO2+H2O→(NH4)2SO3+2H2O+2CO2↑
(NH4)2SO3+S→(NH4)2S2O
【方法三】
其制备方法可通过二硫化碳法或硫磺法制备硫氰酸铵。
二硫化碳法
将二硫化碳和稍过量的液氨同水混合,在压力5.88×105Pa、温度100℃的条件下反应约20h,反应液经减压蒸发脱除硫化氢,在液温105℃时用硫化铵除去铁及重金属,过滤,将滤液减压浓缩后在结晶器内冷却结晶,再经离心分离、干燥,得到硫氰酸铵。反应方程式:CS2+3NH3=NH4SCN+NH4HS
NH4HS=NH3↑+H2S↑
硫磺法
将适量水与硫磺粉在反应器中搅拌成浆状,分次缓慢加入固体氰化钠,在110℃左右进行反应,生成硫氰化钠,再加入固体氯化铵,反应生成硫氰酸铵,再在反应液中加入硫氰酸钡除杂澄清,上层清液经减压蒸发,浓缩析出氯化钠,再经过滤、冷却结晶、分离和干燥,得到硫氰酸铵。反应方程式:NaCN+S=NaSCN
NaSCN+NH4Cl=NaCl+NH4SCN
