Modular reactor

Abstract

Modular microreactors are provided composed of microreactor parts including a plate body which has, on one plate side, a groove-shaped depression in which a reactor tube is accommodated, and the reaction tube has connection ends on the outer sides of the plate body. Also disclosed are reaction tubes for turbulent mixing, kits for producing the reactors and the use thereof for commencing chemical reactions.

The invention claimed is:

 a reaction tube in said depression and positioned completely below said outer surface, said reaction tube having connection ends located at an edge of the plate body, and being spaced from the plate body along an entire length of said reaction tube; and 
 an induction coila thermal transfer medium in said depression between said reaction tube and said plate body. 
 
     
     
       2. The microreactor part according to  claim 1 , wherein the plate body is cuboid. 
     
     
       3. The microreactor part according to  claim 1 , wherein the plate body comprises at least two reaction tubes in the depression. 
     
     
       4. The microreactor part according to  claim 3 , further comprising at least one connection element connected to the connection ends and the edge of the plate body of the at least two reaction tubes, said at least one connection element having one of a fluid inlet and a fluid outlet. 
     
     
       5. The microreactor part according to  claim 3 , wherein the depression has a meander-shaped course and partition walls are provided between meander-shaped portions of the course, the partition walls being sealed together with the plate body, by a plate. 
     
     
       6. A reaction tube comprising: an inner diameter of up to 20 mm and a cross-sectional constriction as a mixing element, the cross-section being constricted on one side of the tube, preferably a round tube, by at least 15%, preferably at least 20%. 
     
     
       7. The reaction tube according to  claim 5 , characterised in that the cross-section of the tube is not enlarged compared to the constriction, preferably also 90° to the constriction, and the cross-section preferably forms a semi-circle at the constriction. 
     
     
       8. The reaction tube according to  claim 5 , which comprises a plurality of cross-sectional constrictions, the side of the cross-sectional constriction preferably changing in an alternating sequence, in particular the cross-sectional constrictions being spiralled or opposingly offset in the tube cross-section, and/or the cross-sectional constrictions preferably being straight, prismatic, cylindrical or spherical. 
     
     
       9. A microreactor comprising:
 at least two microreactor parts, each having a plate body which has an outer surface and a depression formed in said outer surface on one plate side; 
 a reaction tube in said depression and positioned completely below said outer surface, said reaction tube being spaced from said plate body and including connection ends located at an edge of said plate body, wherein ends of said reaction tubes of the at least two microreactor parts are connected via a connection element; and 
 an induction coila thermal transfer medium in said depression between said reaction tube and said plate body. 
 
     
     
       10. The microreactor according to  claim 9 , wherein said connection element comprises at least one of an inlet and an outlet for accommodating reaction fluid into or from the reaction tube, and an inlet or outlet for fluid into or from a channel of the depression. 
     
     
       11. A kit for producing a microreactor comprising;
 at least two microreactor parts having a plate body which each have an outer surface and a depression formed in said outer surface on one plate side of said plate body; 
 a reaction tube in said depression and positioned completely below said outer surface, said reaction tube including connection ends located at an edge of the plate body; 
 a connection element for connecting the reaction tubes of the microreactor parts; and 
 an induction coila thermal transfer medium in said depression between said reaction tube and said plate body. 
 
     
     
       12. The microreactor part according to  claim 1 , wherein at least one of the connection ends comprises a fluid mixer, the fluid mixer being one of a flow breaker, a flow accelerator, a mixing jet or a projecting injection needle. 
     
     
       13. The microreactor part according to  claim 4 , wherein one of the fluid inlet or the fluid outlet of the at least one connection element comprises a fluid mixer, the fluid mixer being one of a flow breaker, a flow accelerator, a mixing jet or a projecting injection needle. 
     
     
       14. The microreactor part according to claim 1, wherein said thermal transfer medium is in said depression between said reaction tube and said plate body along an entire length of said reaction tube.  
     
     
       15. The microreactor according to claim 9, wherein said thermal transfer medium is in said depression between said reaction tube and said plate body along an entire length of said reaction tube.  
     
     
       16. The kit according to claim 11, wherein said thermal transfer medium is in said depression between said reaction tube and said plate body along an entire length of said reaction tube.
