Microscale tubular reactor

In a microscale tubular reactor, Swern oxidations were performed between —20 and 20 °C. Mixing was performed stagewise with a series of rapid mixing functions (see Figure 5.22) [57,58]. First, dimethyl sulfoxide and trifluoroacetic anhydride were contacted in an interdigital micromixer followed by a stainless steel tube reactor Rl. After addition of the alcohol and reaction in reactor R2, the mixture was then contacted with a triethylamine solution and passed through two more reactors (R3 and R4) to complete the reaction. 

In a microscale tubular reactor, Swem oxidations were performed between 20 and 20 °C. Mixing was performed stagewise with a series of rapid mixing functions (see Figure 11.21) [71,73]. First, dimethyl sulfoxide and trifluoroacetic anhydride were...
