78.5% | With toluene-4-sulfonic acid; In dichloromethane; at 20 - 33℃; for 38.5h;Heating / reflux; | (VO 504. 3 G (3. 87MOL) CHLORDIFLUORESSIGSaURE UND 5. 0 G p-Toluolsulfonsaure werden in 775 ml Methylenchlorid gelost und bei Raumtemperatur innerhalb von 30min mit 311. 6 G (6. 76 MOL) Ethanol versetzt (Temperaturanstieg auf 33oC). Man ruhrt 38 h unter Ruckfluss am Wasserabscheider nach und kuhlt auf Raumtemperatur ab. Zur Aufarbeitung wascht man mit Wasser (200 ml), gesattigter Natriumhydrogencarbonatlosung (200 ml) und erneut mit Wasser (200 ml), trocknet uber Natriumsulfat, filtriert und destilliert das Losungsmittel ab. Anschliesend wird durch fraktionierte Destillation WEITER AUFGEREINIGT ;-- Man erhalt 488.9 g (98% ig, 78.5 % der Theorie) an Chlordifluoressigsaureethylester (Siedepunkt 94- 96oC). |
