Sulfur residence tunes

The high temperature pyrolysis of sulfonyl fluonde results in the elimination of sulfur dioxide, although secondary reactions also occur, depending on the residence tune With perfluorooctanesulfonyl fluonde, long residence times result in perfluoro(Cg-Cig) compounds, and shorter residence times lead to perfluoro-hexadecane [98] (equation 65)... 

Although the transformation of acrylonitrile to acrylamide sulfate is carefully controlled by limiting the water content of the medium and the residence tune (5 to 10 min) in the reactor, a small fraction is hydrolysed to acrylic add. This reaction takes place at atmospheric pressve, between 145 and I55 C, in the presence of 85 per cent weight sulfuric acid solution, in an agitated jacketed reactor, with a once-through conversion of more than 95 to 97 per cent...
