制备方法与用途

化学性质：

• 液体。沸点为137-138℃。

用途： 主要用于有机合成，并可用于制备相转移催化剂2-氟-4-甲基苄基三甲基溴化铵。

生产方法： 由2,5-二甲基苯胺（[95-78-3]）经席曼（Schiemann）反应制得。具体步骤如下：将400g 40%的氟硼酸加入到50ml水中，冷却至约0℃，在搅拌条件下缓慢滴加72.5g 2,5-二甲基苯胺，随后滴加亚硝酸钠溶液（由40g亚硝酸钠溶于120ml冰水中配制）。反应完成后静置并过滤。用少量的甲醇-乙醚（1:1）及乙醚各洗涤一次，然后在室温下进行分解（温度不超过30℃）。将分解产物通过水蒸气蒸馏得到油层，再用无水氯化钙干燥，并进行分馏，收集145-147℃的馏分，最终得到2-氟-1,4-二甲苯59g，收率为80%。
