Title (EN) METHOD FOR TREATING MIXED SOLUTION
(FR) PROCÉDÉ DE TRAITEMENT DE SOLUTION MIXTE
(JA) 混合溶液の処理方法
Abstract: front page image
(EN)Provided is a method with which it is possible to safely and cost-effectively treat a mixed solution including a specific fluorine-containing electrolyte and a carbonic acid ester. A tetramethylammonium compound (except for tetramethylammonium salts of fluorocomplexes) is added to a mixed solution including a carbonic acid ester and at least one type of compound selected from the group consisting of lithium hexafluorophosphate, lithium tetrafluoroborate, sodium hexafluorophosphate, lithium hexafluoroarsenate, and lithium hexafluoroantimonate; the tetramethylammonium salt(s) of the fluorocomplex(es) is/are precipitated; and then the precipitate is removed.
(FR)La présente invention concerne un procédé avec lequel il est possible de traiter sûrement et économiquement une solution mixte comprenant un électrolyte contenant du fluor spécifique et un ester d'acide carbonique. Un composé de tétraméthylammonium (à l'exception de sels de tétraméthylammonium de fluorocomplexes) est ajouté à une solution mixte comprenant un ester d'acide carbonique et au moins un type de composé choisi dans le groupe constitué de l'hexafluorophosphate de lithium, le tétrafluoroborate de lithium, l'hexafluorophosphate de sodium, l'hexafluoroarséniate de lithium, et l'hexafluoroantimoniate de lithium; le(s) sel(s) de tétraméthylammonium du/des fluorocomplexe(s) est/sont précipité(s); et ensuite le précipité est séparé.
(JA) 特定のフッ素含有電解質及び炭酸エステル類を含む混合溶液を、安全に、且つ経済的に処理することが可能な方法を提供すること。 ヘキサフルオロ燐酸リチウム、テトラフルオロ硼酸リチウム、ヘキサフルオロ燐酸ナトリウム、ヘキサフルオロ砒酸リチウム及びヘキサフルオロアンチモン酸リチウムからなる群より選ばれる一種以上の化合物と、炭酸エステル類とを含む混合溶液に、テトラメチルアンモニウム化合物(但し、フルオロ錯体のテトラメチルアンモニウム塩を除く。)を添加し、フルオロ錯体のテトラメチルアンモニウム塩を析出せしめた後に、かかる析出物を除去する。
