Measurements of the Mutual Diffusion Coefficients of Gases by the Taylor Method : 8th Report, Measurements on the HFC32-Air, HCFC124-Air, HFC125-Air, HFC143a-Air and HFC43-10 mee-Air Systems

The mutual diffusion coefficients of HFC 32 (CH2F2), HCFC 124 (CHCIFCF3), HFC 125 (CHF2CF3), HFC 143 a (CF3CH3) and HFC 43-10 mee (CF3CHFCHFCF2CF3) into air have been measured in the temperature range 0∼180°C and at atmospheric pressure by the use of the Taylor dispersion method. The mutual diffusio...

Summary:The mutual diffusion coefficients of HFC 32 (CH2F2), HCFC 124 (CHCIFCF3), HFC 125 (CHF2CF3), HFC 143 a (CF3CH3) and HFC 43-10 mee (CF3CHFCHFCF2CF3) into air have been measured in the temperature range 0∼180°C and at atmospheric pressure by the use of the Taylor dispersion method. The mutual diffusion coefficient decreases as HFC 32 > HFC 143 a > HFC 125 > HCFC 124 > HFC 43-10 mee. The present results can also be generalized by our generalization method for the mutual diffusion coefficients of the halogenated-hydrocarbon refrigerants into air based on the principle of corresponding states.
