1,1-dichloroethane containing a compound having a nitro group and/or a hydroxyl group as a stabilizer is brought into contact with zeolite having an average pore size of 3.4 to 11A and/or a carbonaceous adsorbent having an average pore size of 3.4 to 11A in a liquid phase. A stabilizer contained in 1,1-dichloroethane is efficiently removed by a simple and convenient method and 1,1-difluoroethane can be economically produced. |
