In the present work, we investigated experimentally the formation mechanism of the phase separation structures and convection patterns in a layer of an isobutyric acid (IBA)-water binary mixture subjected to vertical temperature and concentration gradients. As a result, the formation mechanism of the polygonal cellular patterns with one droplet formed in a certain range of temperature gradient was speculated to be due to the Marangoni effect along the droplet surface. In addition, it was found that the average diameter of the phase-separated droplets depends on initial concentration gradient.
