Abstract

Process for the production of olefins, included in the general formula Rf- CH- CF2 by means of the pyrolysis of acids of the type Rf-CHF-CF2-COOH, where it is a fluorine atom or a perfluorinated alkyl group containing from 1 to 10 carbon atoms, characterized in that the pyrolysis of said acids is carried out at a pressure below atmospheric, preferably at a pressure of less than 400 mm. Hg. (Machine-translation by Google Translate, not legally binding)
