| titleOfInvention | Method for purifying 1,1-difluoroethane and use thereof |
| abstract | PROBLEM TO BE SOLVED: To provide a method capable of industrially advantageously producing high purity 1,1-difluoroethane that can be used as a low-temperature refrigerant or etching gas. A crude 1 containing at least one compound selected from the group consisting of unsaturated compounds containing two carbon atoms in the molecule and saturated chlorine-containing compounds containing two carbon atoms in the molecule. , 1-difluoroethane, a zeolite having an average pore diameter of 3 to 6 and a silica / aluminum ratio of 2.0 or less and / or a carbonaceous adsorbent having an average pore diameter of 3.5 to 6 The adsorbent is contacted to reduce the content of the compound contained as impurities in the crude 1,1-difluoroethane. [Selection figure] None |
