Abstract
Multiphasic reactions, especially those reactions using a phase transfer catalyst, are conducted in microchannel apparatus. Advantageously, these reactions can be conducted with two, planar microlayers of reactants in adjacent laminar flow streams. Microchannel apparatus and methods for conducting unit operations such as reactions and separations in microchannel apparatus is also described. Microchannel apparatus can provide advantages for controlling reactions and separating products, solvents or reactants in multiphase reactions.
Claims18
A method of conducting a chemical reaction, comprising:
- passing a first stream and second stream into a reactor channel;
- wherein the first stream has a thickness of 1 mm or less and a length of more than 3 mm through the reaction channel;
- and wherein the second stream is adjacent to the first stream and has a thickness of 1 mm or less and a length of more than 3 mm through the reaction channel;
- wherein the first stream and the second stream form a combined multiphase stream having a thickness of 2 mm or less and a length of more than 3 mm;
- wherein the first stream comprises a first reactant;
- wherein the second stream comprises a second reactant;
- and
- providing a phase transfer catalyst;
- wherein the phase transfer catalyst catalyzes the reaction of the first reactant and the second reactant to form a product.
