N-乙酰基硫脲制备
1.由硫脲和乙酰氯反应而得。在带回流冷凝器的三口烧瓶中，加入38g硫脲，40g乙酰氯及500ml甲苯。在油浴上搅拌回流16h(不再放出氯化氢为止)蒸除甲苯，剩余物用其三倍的乙醇重结晶。得产品19g，熔点163-165℃,产率34%。
2.
将1.1摩尔的硫帆化钠溶于500毫升热丙酮中，然后慢慢滴加1摩尔乙酞氯，加热，至乙酞氯的气味消失为止(约10分钟)。冷却，滤去氯化钠沉淀。在搅拌下，将150毫升28%的氨水慢慢加入到滤液中，然后蒸发至干。残余物用热乙醇萃取，所得粗产品在乙辞中重结晶，
也可将硫氰化钠和乙酸氯置于甲苯中回流I小时，乙醇中童结晶，得菱形晶休，熔点 165℃，产率34%.
