硫代硫酸铵制备
1.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。
2.由碳酸氢铵与二氧化硫和水作用生成亚硫酸铵,再与硫黄反应,经过滤、蒸发、冷却结晶、分离,所得硫代硫酸铵。或者在硫酸铵水溶液中,加入五硫化铵及过量氨水,反应后,过滤除硫,然后在低温下真空蒸发,得硫代硫酸铵。
3.将过量的碳酸铵加到硫代硫酸钙水溶液中,过滤除去沉淀,将滤液在50℃的恒温水槽中放置两日,使过剩的碳酸铵分解。然后在30℃下进行减压蒸发,浓缩结晶。分离出的结晶夹在滤纸间在五氧化二磷上减压干燥,可制得无水物。
4.按准确的物质的量比为1∶2的比例将硫化氢铵与亚硫酸氢铵水溶液混合后在室温下进行反应,即可生成硫代硫酸铵。反应中也有少量硫析出,通过水浴加热使硫沉降,过滤除去。滤液按上一方法相同步骤进行蒸发浓缩,分离出的结晶夹在滤纸中干燥。
