Method for producing difluoroacetyl chloride

二氟乙酰氯的制造方法

Abstract

本发明的二氟乙酰氯的制造方法包括使至少含有二氟乙酰氟的二氟乙酰氟组合物在能够反应的温度下与氯化钙接触的氯化工序。另外,本发明的2,2-二氟乙醇的制造方法包括使上述方法所得到的二氟乙酰氯催化还原的催化还原工序。采用这些方法,能够由二氟乙酰氟高效率地制造二氟乙酰氯和2,2-二氟乙醇。
The disclosed method for producing difluoroacetyl chloride includes a chlorinating step that brings a difluoroacetyl fluoride composition containing at least difluoroacetyl fluoride into contact with calcium chloride at a temperature at which a reaction can take place. Also, the disclosed method for producing 2,2-difluoroethyl alcohol includes a catalytic reduction step for catalytically reducing the difluoroacetyl chloride obtained by the abovementioned method. By means of these methods, it is possible to efficiently produce difluoroacetyl chloride and 2,2-difluoroethyl alcohol from difluoroacetyl fluoride.
