viscosity, refractive index, surface tension, and thermal decomposition of aqueous n-尊龙凯时·中国官方网站

in this work, physical properties such as dynamic viscosity at （298.15 to 338.15） k, surface tension, andrefractive index at temperatures （303.15 to 333.15） k of pure and aqueous nmethyldiethanolamine （mdea） solutions （with mass fraction of mdea of 0.3228 and 0.4880） were measured at atmospheric pressure and correlated. a thermogravimetric analyzer （tga） was used to study the thermal stability of solvents in the presence of nitrogen （20 ml· min-1）, at a heating rate of 10 °c· min-1.
