Abstract

In this work we present the first results related to production of water nanoemulsion in diesel oil using microfluidic reactors as tool. We tested two different microreactors, a vortex and 3D serpentine geometry, varying parameters such as total flow rate, surfactant concentration and ratio between phases. It was observed water droplets sizes from 100 to 700 nm, and the stability was dependent of surfactant concentration. Higher flow rates offer smaller droplets sizes obtained in vortex device. However, with 3D serpentine we observed nanoemulsion with better stability.
