A New Synthesis of 1,2-Dialkoxyethanes

Liquid Densities, Kinematic Viscosities, and Heat Capacities of Some Alkylene Glycol Dialkyl Ethers

“…To complete our previous works, − we report experimental measurements of liquid densities at 1 MPa and kinematic viscosities at atmospheric pressure in the temperature range from (283.15 to 423.15) K and heat capacities at 1 MPa from (312.57 to 421.48) K for monoethylene glycol diethyl ether, diethylene glycol diethyl ether, diethylene glycol dibutyl ether, triethylene glycol dibutyl ether, and dipropylene glycol dimethyl ether. Most of the properties reported in the literature for these substances correspond to densities and viscosities at ambient conditions, − except the data of Ku and Tu for monoethylene glycol diethyl ether and diethylene glycol diethyl ether in the range (288.15 to 343.15) K and those of Vogel for densities of diethylene glycol diethyl ether in the range (289 to 361) K. Concerning heat capacity, the only data available in the literature are those of Villamañan et al and Kusano et al for monoethylene glycol diethyl ether at ambient temperature and Zábranský et al for diethylene glycol diethyl ether in the range (280 to 310) K.…”
