Diffusion Coefficients: C2H6
Binary diffusion coefficients for gas-gas, gas-liquid (dissolved gas in water), and liquid-liquid (solute in water) systems — gas-gas D in cm²/s at 1 atm; gas-liquid D in cm²/s (×10⁻⁵ range); liquid-liquid D in m²/s (×10⁻⁹ range); all at or near 25°C reference; per Marrero & Mason, Cussler, Perry's, CRC Handbook
