CAS: 541-58-2
分子式: C5H7NS
分子量: 113.18
沸点: 144-146℃
中文名称: 
2,4-二甲基噻唑
二甲基硫杂茂
英文名称: 
2,4-dimethyl-Thiazole
2,4-Dimethylthiazole
2,4-methylthiazole
2,4-dimethyl-thiazol
Thiazole,2,4-dimethyl-
2,4-dimethyl-thiazole
2,4-dimethyl thiazole
性质描述: 液体具有吸湿性。沸点144-145℃(95.9kPa),70-73℃(6.67kPa),相对密度1.0562(15/4℃),折光率1.5091。溶于醇、醚及冷水,在热水中溶解度稍小。
生产方法: 由乙酰胺与五硫化二磷反应,再与氯化丙酮缩合而得。将无水苯加入反应瓶中,再加入乙酰胺和粉状五硫化二磷的混合物,在水浴上加热。再加上氯代丙酮的苯溶液,加完回流30分钟。然后将水加入反应混合物中,即分层,弃去上层微红色液体,取下层液加氢氧化钠使呈碱性,再加乙醚提取。提取液用无水硫酸钠干燥。过滤,常压蒸馏,收集140-150℃馏分,再将收集物重新蒸馏,收集143-145℃馏分即为2,4-二甲基噻唑。
用途: 用作有机合成中间体。
