A study has been carried out on the effects that some operational parameters have on the conversion and the reaction rate in the addition of 1-iodoperfluorohexane to vinyl acetate. The reaction was carried out at 80 °C using azobisisobutyronitrile (AIBN) as initiator; the parameters examined were: the molar ratio of the reagents, the reaction time and te AIBN concentration in the reaction mixture. High molar ratios of vinyl acetate to 1-iodoperfluorohexane give high conversions, but favour the formation of a by-product, therefore reducing the adduct yield. The operational conditions leading to the optimum adduct/by-product yield ratio were definited. Complete conversion of 1-iodeperfluoro-hexane was obtained in short time (10-15 minutes) using AIBN concentrations of about 5% by weight.

Abstract
A study has been carried out on the effects that some operational parameters have on the conversion and the reaction rate in the addition of 1-iodoperfluorohexane to vinyl acetate. The reaction was carried out at 80 °C using azobisisobutyronitrile (AIBN) as initiator; the parameters examined were: the molar ratio of the reagents, the reaction time and te AIBN concentration in the reaction mixture. High molar ratios of vinyl acetate to 1-iodoperfluorohexane give high conversions, but favour the formation of a by-product, therefore reducing the adduct yield. The operational conditions leading to the optimum adduct/by-product yield ratio were definited. Complete conversion of 1-iodeperfluoro-hexane was obtained in short time (10-15 minutes) using AIBN concentrations of about 5% by weight.
