実施例2
(FSOCFCFOCF=CFの製造例)
温度計ホルダー、2本のジムロート冷却管、滴下ロートを装備した100mlの4つ口フラスコに30mlのジグライム、3gのKFを加え、フラスコを0℃に冷却し、攪拌した。滴下ロートよりβ−サルトン(30g、167mmol)を加え、続いて1,1,3−トリクロロ−2,3,3−トリフルオロ酸化プロピレン(35.6g、166mmol)を加えた。滴下後、0℃で1時間攪拌した後、40度で2時間攪拌させた。攪拌を停止させ、30分間静置させ、二層分離した下層(58.2g)を抜き出した。下層の19F−NMR分析を行ったところ、純度88%のFSOCFCFOCF(CFCl)COClであることが分かった(収率78%)。
Example 2
(Production example of FSO 2 CF 2 CF 2 OCF = CF 2 )
30 ml of diglyme and 3 g of KF were added to a 100 ml four-necked flask equipped with a thermometer holder, two Dimroth condensers, and a dropping funnel, and the flask was cooled to 0 ° C. and stirred. Β-sultone (30 g, 167 mmol) was added from the dropping funnel, followed by 1,1,3-trichloro-2,3,3-trifluoropropylene oxide (35.6 g, 166 mmol). After dropping, the mixture was stirred at 0 ° C. for 1 hour and then stirred at 40 ° C. for 2 hours. Stirring was stopped, the mixture was allowed to stand for 30 minutes, and the lower layer (58.2 g) separated into two layers was extracted. A 19 F-NMR analysis of the lower layer revealed that it was 88% pure FSO 2 CF 2 CF 2 OCF (CF 2 Cl) COCl (yield 78%).

NaCO(17.9g、169mmol)を200mlの水で溶かしたNaCO水溶液に上記で得られたFSOCFCFOCF(CFCl)COClを室温で滴下した。4時間攪拌した後、内溶液をろ過し、ろ液を減圧下で乾燥させた。得られた固体を20mlのクロロホルムで洗浄し、さらに乾燥させた。これにより得られた固体は、FSOCFCFOCF(CFCl)COONaで表されるカルボン酸塩であった。 FSO 2 CF 2 CF 2 OCF (CF 2 Cl) COCl obtained above was added dropwise at room temperature to a Na 2 CO 3 aqueous solution in which Na 2 CO 3 (17.9 g, 169 mmol) was dissolved in 200 ml of water. After stirring for 4 hours, the inner solution was filtered, and the filtrate was dried under reduced pressure. The obtained solid was washed with 20 ml of chloroform and further dried. The solid thus obtained was a carboxylate represented by FSO 2 CF 2 CF 2 OCF (CF 2 Cl) COONa.

蒸留装置の装備された200mlのフラスコに上記で得られた固体(52g)と100mlのジグライムを入れ、140℃に加熱した。沸点が75〜80度の蒸留分を採りだし、その成分をGC−Mass分析及び19F−NMR分析を行ったところ98%のFSOCFCFOCF=CFと2%のFSOCFCFOCHFCClFであることが分かった。
FSOCFCFOCF=CFの全収率は69%であった。
The solid (52 g) obtained above and 100 ml of diglyme were placed in a 200 ml flask equipped with a distillation apparatus and heated to 140 ° C. Distillate having a boiling point of 75 to 80 degrees was taken out, and its components were subjected to GC-Mass analysis and 19 F-NMR analysis. As a result, 98% FSO 2 CF 2 CF 2 OCF═CF 2 and 2% FSO 2 CF 2 CF 2 OCHFCClF 2 was found.
The overall yield of FSO 2 CF 2 CF 2 OCF═CF 2 was 69%.
