- 用途一:用作染料中间体
- 上游原料:对甲氧基苯胺 --> 硫氰酸钠 --> 搪玻璃反应锅 --> 刚果红试纸 --> 工业盐酸
- Alfa Aesar:4-甲氧基苯硫脲,96% N-(4-Methoxyphenyl)thiourea, 96%(2293-07-4)
- Hazard Note:Irritant
- 方法一:由对甲氧基苯胺盐酸盐与硫氰酸钠加成而得。在搪玻璃反应锅内加水350L,加热至60℃,在搅拌下加入220kg对甲氧基苯胺,使其完全溶解。再加入220kg30%的工业盐酸,使料液对刚果红试纸呈微蓝色,维持10min后再加入166.7kg(以100%计)硫氰酸钠。加热,慢慢升温到105℃,回流24h。然后冷到25℃以下过滤,滤饼用水洗涤,干燥得300kg对甲氧基苯基硫脲。
- 用途二:用作有机合成中间体,主要用于染料工业。
