Abstract

A találmány tárgya ipari méretű eljárás fluorozott diciano-benzolokelőállítására, az eljárás során kiindulási anyagként tetraklór-diciano-benzolt használva. A találmány szerint eljárva a fluorozottdiciano-benzolokat magas hozammal kapják oly módon, hogy a tetraklór-diciano-benzolt valamely fluorozó reagenssel, a tetraklór-diciano-benzol tömegére vonatkoztatva 0,1-3-szoros mennyiségű, nem-protikuspoláros oldószer jelenlétében reagáltatják. A találmány szerintieljárás hatásfokát tovább növelhetjük oly módon, hogy areakciókeverékbe foglalt nagymennyiségű szilárd anyagot aprítjuk vagyeltávolítják. Ó
