example 1

[0048] As shown in FIGS. 1A to 1C , two rectangular acrylic resin plates 2A and 2B (KURALEX S manufactured by NITTORESIN INDUSTRIES: length 76 mm×width 100 mm×height 8 mm) were superimposed on each other. As a mounting portion on which the integral connector is to be mounted, two portions having dimensions of length 16mm×width 16mm×height 8mm were cut out from the center of the side portion of the resin plate including the overlapping portion, thereby forming two opposing cutout portions. Then, microchannels (width: 500 μm, depth: 100 μm) were linearly formed in the acrylic resin plate 2A by using an end mill. Thereafter, the acrylic resin plates 2A and 2B were ultrasonically melt bonded together by diffusion bonding, resulting in a microreactor body with microchannels in the bonded surface.

[0049] In order to fix each integral connector to the microreactor body, a drill is used to drill holes at four positions centered on the end of the microchannel in a corresponding one o...

example 2

[0052] As shown in FIGS. 2A to 2C , a microreactor device was fabricated in the same manner as in Example 1, except that the two mounting portions for the integral connector were not cut. Thus, a microreactor device is obtained in which the integral connector is installed while protruding from the side of the microreactor body 12 .

[0053] Operational performance is the same as Example 1.

example 3

[0055] Such as image 3 As shown, a semicircular microchannel 21 is formed in the microreactor body 20, and the integral connector 5 is arranged such that the tangential direction of the channel end coincides with the direction of the supply / discharge pipe. Otherwise a microreactor device was fabricated in the same manner as in Example 2.

[0056] Operational performance is the same as Example 2.

Abstract

A microreactor apparatus includes; a microreactor body that includes first and second substrates; a microchannel that is formed inside the microreactor body; and integral connectors that are disposed detachably on the microreactor body, and through which supply / discharge pipes are to be connected to end portions of the microchannel, respectively.

Description

technical field [0001] The present invention relates to a microreactor device having an integral connector, a supply / discharge pipe for supplying a reaction fluid (liquid or gas) to said microreactor device or discharging a reaction fluid from said microreactor device Connect to the microreactor body through the integral connector. [0002] Background technique [0003] Microreactor is a general term for small reactors, which are also called microchannel reactors or microfluidic devices, and generally have microchannels of several micrometers to hundreds of micrometers. Most chemical reactions using microreactors take place in flow systems. As a microreactor body for forming microchannels, various materials such as glass, plastic, metal, and silicon can be used. In order to observe the flow or reaction in the microchannel from the outside, it is convenient to use a transparent material such as glass or plastic. [0004] The microreactor body requires connectors for connec...
