| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method of removing hydrochloric acid, from a product comprising trifluoroethylene and hydrochloric acid, without generating hazardous substance, and thus purifying trifluoroethylene.SOLUTION: A method of purifying trifluoroethylene has a step of bringing a gas composition comprising trifluoroethylene and hydrochloric acid into contact with an acid component removal liquid with an alkali concentration of 40 mass% or less to remove the hydrochloric acid. The acid component removal liquid may be water.SELECTED DRAWING: Figure 1
【課題】トリフルオロエチレンと塩化水素を含む生成物から、有害物質を発生させることなく塩化水素を除去し、トリフルオロエチレンを精製する方法の提供。【解決手段】トリフルオロエチレンと塩化水素を含むガス組成物を、アルカリ濃度が４０質量％以下の酸成分除去液と接触させ、前記塩化水素を除去する工程を有するトリフルオロエチレンの精製方法。酸成分除去液は水でもよい。【選択図】図１ |
