1,1,1,2-Tetrafluoropropane synthesis

11synthesis methods
-

Yield:431-31-2 87.2 %Chromat. ，421-48-7 10.7 %Chromat.

Reaction Conditions:

with hydrogen;0.5% Pd/C at 225;Flow reactor;

Steps:

2

Example 2; Reaction of H? with CFC-215bb over Palladium on Carbon catalyst; Example 1 was substantially repeated except that the catalyst was commercial 0.5% palladium on carbon (5.4g, 15.0ml) and only hydrogen and CFC-215bb were fed to the reactor. The hydrogen to CFC-215bb mole ratio was 2/1 and the contact time was 30 seconds. The GC/MS analytical results of the products, in area%, for various operating temperatures are summarized in Table 2. Minor amounts of other compounds, not listed in Table 2 were also present. TABLE 2
