Surface tension of dimethoxymethane and methyl tert-butyl ether

The surface tension of dimethoxymethane was measured at temperatures from (238 to 388) K with a differential capillary rise method (DCRM), together with the surface tension of methyl tert-butyl ether measured at temperatures from (243 to 393) K. The uncertainty of temperature is less than +/- 10 mK (ITS-90). The uncertainty of surface tension measurements was estimated to be within +/- 0.2 mN, m(-1). The results were correlated as a function of temperature, and the average absolute deviations were 0.059 mN, m(-1) for dimethoxymethane and 0.050 mN, m(-1) for methyl tert-butyl ether, respectively.
