The invention disclose a hydrogen fluoride containing composition comprising hydrogen fluoride and a compound which is liquid in the standard state (25 °C, 1 atmosphere) and has a boiling point of 120 °C or more and pka of 12 or more at 25 °C, and use of the composition for a fluorination agent.
The compound which can be preferably used is represented by the formula (1):
wherein R1 to R4 are a substituted or unsubstituted alkyl or aryl group and can be the same or different, and R1 or R2 or R3 and R4 can bond to form a ring having a nitrogen atom or a nitrogen atom and other hetero atom, or R1 and R3 can bond to form a ring having a nitrogen atom or a nitrogen atom and other hetero atom.
The fluorination agent of the invention exerts effect with a similar reaction mechanism to hydrogen fluoride, can be applied to the halogen exchange reaction of a halogen containing organic compound, and can produce a fluorine containing compound with safety and ease without specific equipment or technique.
本发明公开了一种含氟化氢的组合物,该组合物包括氟化氢和一种在标准状态(25℃,1 个大气压)下为液态、沸点为 120℃或以上、25℃时 pka 为 12 或以上的化合物,以及该组合物在氟化剂中的用途。
可优先使用的化合物由式(1)表示:
其中 R1 至 R4 是取代或未取代的烷基或芳基,可以相同或不同,R1 或 R2 或 R3 和 R4 可以键合形成具有氮原子或氮原子和其他杂原子的环,或 R1 和 R3 可以键合形成具有氮原子或氮原子和其他杂原子的环。
本发明的氟化剂与氟化氢的反应机理相似,可用于含卤有机化合物的卤素交换反应,无需特定的设备或技术,即可安全、方便地生产出含氟化合物。
