Flow Reactor for Thermal Crosstalk

Abstract

A flow reactor having a module (12) comprising at least first (20), second (30) and third (40) parallel plates temporarily or permanently stacked together and each parallel The plates define a first thermal fluid layer (25) between the first plate (20) and the second plate (30) and a process fluid layer ( 35), the process fluid layer (35) comprises a process fluid channel (32), the process fluid channel (32) has two or more U-shaped bends and three or more continuous process fluid channels segments, the continuous process fluid channel segments are connected by corresponding U-shaped bends, the first thermal fluid layer (25) comprises at least two open thermal fluid channels (26) in the second plate (30), At least two open channels (26) are located between respective adjacent process fluid channel segments when viewed in plan view of the module (12).

Description

[0001] This application, pursuant to 35 U.S.C. §119, claims the benefit of priority to U.S. Provisional Application Serial No. 62 / 173,612, filed June 10, 2015, the contents of which are based upon and incorporated by reference in its entirety . Background technique [0002] Currently, the world is dealing with depleting infrastructure, such as energy and fresh water, and realizing rising raw material costs. Therefore, improving the sustainability and efficiency of fine chemical and pharmaceutical synthesis processes has become increasingly important. A solution embodied by the use of continuous small-scale flow reactors that enable the use of less reagents, generate less waste, higher throughput, higher efficiency, increased safety and reduced environmental impact. The use of such continuous flow devices avoids the disadvantages associated with conventional "batch" synthesis or scale-up when moving from laboratory to market-scale production. [0003] Continuous flow micro / mi...

[0005] However, the high thermal conductivity of flow reactors can also be a disadvantage

This is because the desire to have as much channel length and channel volume as possible within a given reactor module makes it desirable to use process channels with folded geometries, but at the same time folded channels are at risk of thermal crosstalk where along A large amount of heat is generated (or absorbed) at one location in the process channel, and the heat (or cold spot) spreads to other locations along the process channel, which has adverse effects
