The experiments reported here show how diffusion rates in liquids can be increased by as much as an order of magnitude by use of coupled diffusion fluxes in mixed solvents. Solutes whose diffusion can be accelerated in this way include simple electrolytes, essential oils, dyes, and antibiotics. These increases are primarily caused by thermodynamic interactions and can be estimated from solubilities.
