Abstract

Szerves vegyületek (pl. szerves fluorvegyületek, mint pl. fluor-karbonsavak vagy karbonsav-kloridok) csekély mennyiségben karbonsav-fluoridokat, hidrogén-fluoridot, illetve hidrolizálható fluoridottartalmazhatnak. Származékképzésnél (pl. észterezésnél) korrozívfluoridok, illetve hidrogén-fluorid képződnek. A találmány tárgyaeljárás szerves fluorvegyületek (pl. karbonsavak, karbonsav-kloridokés származékaik pl. karbonsav-észterek) előállítására a megfelelő,sav-fluoridokat, illetve hidrolizálható fluoridot tartalmazókarbonsav-kloridokból és alkoholokból, a karbonsavak <onium<-sóinakkatalitikus hatása mellett. A találmány szerinti eljárással fluoridbanszegény termékeket nyernek. Alternatív módon szervetlen oxidszerűszorbenseket alkalmaznak. Az eljárás különösen előnyösen alkalmas atrifluor-ecetsav, klór-difluor-ecetsav, trifluor-acet-ecetsav ésdifluor-acet-ecetsav észtereinek előállítására. Ó
