Chemical microreators for chemical systhesis and their methods of manufacture are known, but have disadvantages such as extremely high manufacturing costs or poor flexibility for adaptation to various cases of application. These disadvantages are avoided by means of the microreators and manufacturing methods according to the invention. The microreators are characterized in that the reactors contain fluid ducts in at least one plane as well as feed and return lines for fluids, wherein the fluid ducts are defined by side walls of metal opposing each other and further side walls of metal or plastic extending between said side walls, and in which the planes are connected together and/or with a closure segment closing open fluid ducts by means of appropriate solder or adhesive layers. The manufacturing method is characterized by process sequences in which the individual reactor planes produced by means of electrolytic methods, are connected together by soldering or gluing.
Manufacturing process for chemical microreactors, including at least one substrate with fluid ducts as well as feeding and drain conducts for fluids without using plastic moulding techniques comprising the following steps of:
Manufacturing process for chemical microreactors, including at least one substrate with fluid ducts as well as feeding and drain conducts for fluids without using plastic moulding techniques comprising the following steps of:
Manufacturing method for chemical microreactors, including at least one substrate with fluid ducts as well as feeding and drain conducts for fluids without using plastic moulding techniques comprising the following process steps of:
Method according to any one of the preceding claims characterized in that a substrate with surfaces consisting of at least a metal selected from the group consisting of steel, stainless steel, copper, nickel and aluminium, is used.
Method according to any one of the preceding claims, characterized in that passages are formed inside the substrates.
Method according to any one of the preceding claims, characterized in that after superimposing and interconnecting the substrates the surfaces of the fluid ducts are modified by at least a method, selected from the group consisting of metal deposition, metal etching and absorbing of chemical compounds or of other chemical species.
Method according to any one of the preceding claims, characterized in that valves and/or other actors are formed in the reactors by application of ferromagnetic metal layers.
Method according to any one of the preceding claims, characterized in that sensors for measuring properties of flowing fluids and/or electrical lines are formed in the reactors.
Method according to any one of the preceding claims, characterized in that electrical resistive heating systems and/or cooling elements are formed in the reactors.
Method according to any one of the preceding claims, characterized in that in in individual layers of the microreactor consisting of a plurality of substrates, the metal is totally removed in defined areas by etching-off in order to form translucent windows.
Chemical microreactor with fluid ducts in at least one plane as well as feeding and drain conducts for fluids, in which the fluid ducts are defined by side walls of metal opposing each other and by further side walls of metal or plastic extending between said side walls, characterized in that the planes are connected together and/or with a closure segment closing open fluid ducts by means of appropriate solder and/or adhesive layers.
