Abstract

In a micro chemical apparatus, guide walls as physical barriers are provided at a region where fluid A and fluid B as unmixed raw materials and a product are discharged so that, when the fluid A and the fluid B as raw materials are charged, only the portion in which the fluid A and the fluid B are mixed and allowed to react with each other by molecular diffusion of the raw materials is discharged. As a result, only the product is in the range between the two guide walls, and the product can be selectively taken out of the outlet.

Claims (9)

1. A micro chemical apparatus comprising:

a channel defined by a top wall, a bottom wall and opposing side walls, the channel having raw material inlet ports and outlet ports; and

guide walls provided in a part of the channel in the direction of travel of raw materials input through the raw material inlet ports so that a composition of each material to be discharged passing through each outlet port formed in the channel is different for every outlet port depending on a material distribution in a horizontal plane perpendicular to the direction of the travel of the raw materials in the channel in order to form physical barriers at a region where the material distribution is generated,

wherein the horizontal plane perpendicular to the direction of travel of the raw materials is divided into two or more by the guide walls as the outlet ports,

wherein, within another part of the channel where the guide walls are not provided, the material distribution comprises the raw materials as unmixed and a product or a mixture of the raw materials, and the guide walls are configured such that the raw materials and the product or the mixture of the raw materials are separately discharged through different outlet ports,

wherein the guide walls extend from the top wall to the bottom wall and are horizontally displaced from each other.

2. The micro chemical apparatus according to claim 1 , wherein the tip of the guide wall has a tapered shape.

3. The micro chemical apparatus according to claim 1 , comprising a temperature control part which maintains the temperature of raw materials or a product traveling in the micro chemical apparatus at a desired temperature.

4. The micro chemical apparatus according to claim 2 , comprising a temperature control part which maintains the temperature of the raw materials or the product traveling in the micro chemical apparatus at a desired temperature.
