Document Type and Number:
WIPO Patent Application WO/2021/049605
Kind Code:
A1
Abstract:
According to the present invention, impurities are removed from a fluoroolefin having a =CF2 or =CHF structure, the fluoroolefin containing, as the impurities, haloalkenes and/or haloalkanes and/or haloalkynes obtained by a dehydrohalogenation reaction. Provided are: a method, for purifying the fluoroolefin having a =CF2 or =CHF structure, which includes a step for bringing into contact, with a solid adsorbent, the fluoroolefin having a =CF2 or =CHF structure and containing at least one type of impurity from among haloalkanes and/or haloalkenes and/or haloalkynes obtained by a dehydrohalogenation reaction, and adsorption-removing the impurities; a high-purity fluoroolefin; and a manufacturing method therefor.
