- a metal such as silver, copper, zinc, etc. may be added to the catalyst.
- the catalyst In the hydrogenation reaction in the liquid phase, 1 to 30% by weight, preferably 3 to 20% by weight of the catalyst is charged into the pressurized reaction vessel based on HFC-1336, and hydrogen is charged after deaeration of the system. .
- the pressure of hydrogen is not particularly limited, but is considered in view of the economics of the reactor. However, 5 to 30 kg / cm 2 G is preferable.
- Hydrogen may be added as the reaction proceeds. Hydrogen is sufficient for 1 to 1.5 moles per mole of HFC-1336.
- the reaction temperature is preferably from 0 to 200 ° C, particularly preferably from 0 to 100 ° C. Solvents can also be used. As the solvent, those similar to the above solvents and alcohols such as methanol, ethanol, and isopropanol can be used.
