Procedure

Use is made of a vessel with a volume of 1 litre comprising 1000 g of a water and KOH mixture in which the KOH is present at 75% by weight. HFC-245eb is introduced continuously into the mixture, maintained at 160° C., for 2 hours with a flow rate of 138 g/h and a conversion of HFC-245eb of 83% is obtained for a selectivity for HFO-1234yf of 100%. The pressure is 1 bar.
