Disclosed is a mixture of fluoroolefin iodides represented by the general formulae: C n F2n+1CF2CH=CF(CF2CF2)m I [Ia] and C n F2n-1CF=CHCF2(CF2CF2)m I [Ib] wherein n is an integer of 0 to 5, and m is an integer of 1 to 3. The fluoroolefin iodide mixture is produced by subjecting a fluoroalkyl iodide represented by the general formula: C n F2n+1CF2CH2CF2(CF2CF2)m I [II] wherein n is an integer of 0 to 5, and m is an integer of 1 to 3, to an HF-elimination reaction in the presence of a basic compound.

L'invention porte sur un mélange d'iodures d'oléfines fluorées représenté par la formule générale (Ia) : CnF2n+1CF2CH=CF(CF2CF2)mI et la formule générale (Ib) : CnF2n+1CF=CHCF2(CF2CF2)mI (dans lesquelles n représente un entier de 0-5 et m représente un entier de 1-3). Le mélange d'iodures d'oléfines fluorées est produit par déshydrofluoration d'un iodure de fluoroalkyle représenté par la formule générale (II) : CnF2n+1CF2CH2CF2(CF2CF2)mI (dans laquelle n représente un entier de 0-5 et m représente un entier de 1-3) en présence d'un composé basique.
