Abstract:
During the past years, microtechnologies have been extensively used in Chemical reactions. In these systems, using an optimal system for separation, and purification of Chemical Products is of great importance. In this study, we have focused on the separation of organic-phase and aqueous-phase Products in 26 fabricated microsystems. The fabrication method of the glass microseparators consists of Lithography, Acidization, and Glass-to-Glass Thermal Connection. We have also studied key parameters of organic and aqueous phase separation in continuous capillary microseparators like the width of the capillary channel, length of the capillary channel, number of the capillary channels, and flow of the inlet fluids. The results show that to separate these phases, two pressure equations must be satisfied. Detailed examination on width, length, and the number of the capillary channels alongside the flow of organic and aqueous phases, showed that reducing the width of the capillary channels, accretion in the number of capillary channels, and increasing the flow of the aqueous phase results in increasing the yield of separation.
