The paper aims to examine the effect focus ratio on the focus width of the microchannel and mixture efficiency on the glycerol nitration. In this study is using two microchannels. First, by measuring the flow mixing. Second, by measuring the temperature, using a K-type thermocouple connected to Analog Converter Data. The independent variable is the focus ratio of the inlet channel. Focus ratio of 1:2 (DSheath=300 m), focus ratio of 1:1(DSheath=150 m), the focus ratio of 2:1 (DSheath=75m).

The smaller the focus ratio, the higher the mixture efficiency, and the smaller the width of focus. Diffusion-related to the speed of reaction, the flow shear stress influenced by differences in the volume of the inlet channel, the greater of shear stress will accelerate the diffusion of molecules-the smaller the focus ratio, the more increase the reaction temperature.
