    • This process for producing fluorine-containing compounds includes liquid-phase fluorination by introducing a raw material compound and fluorine gas into a solvent to replace hydrogen atoms in the raw material compound with fluorine atoms. More specifically, the process for producing fluorine-containing compounds includes (1) promoting fluorination by dissolving the raw material compound in anhydrous hydrofluoric acid and introducing into a liquid-phase fluorination solvent, or (2) promoting fluorination by dissolving the raw material compound in a perfluoro compound having a plurality of polar groups in a molecule thereof and introducing into a liquid-phase fluorination solvent. According to these processes, a fluorination reaction can be carried out at high yield and without containing hardly any isomers while using a hydrocarbon compound as is for the raw material.
    • 该含氟化合物的制造方法包括通过将原料化合物和氟气引入溶剂中来代替原料化合物中的氢原子用氟原子进行液相氟化。 更具体地说,制造含氟化合物的方法包括:(1)通过将原料化合物溶解在无水氢氟酸中并引入液相氟化溶剂来促进氟化,或(2)通过将原料化合物溶解于 在其分子中具有多个极性基团并引入液相氟化溶剂的全氟化合物。 根据这些方法,氟化反应可以以高产率进行,并且在使用原料的烃化合物的同时不含有几乎任何异构体。
