Abstract
Abstract Glycerol (and activated forms such as epichlorohydrin) provide a versatile substrate for the design and synthesis of new, bio-derived compounds that can have uses in key contemporary applications such as CO2 capture, plastics recycling, and green chemistry in general. Upon etherification of one or more alcohols the glycerol skeleton, the thermophysical properties of the resultant substances change dramatically compared to glycerol. Most notably, the viscosity of glycerol-derived diethers and triethers is reduced by 2-3 orders of magnitude, however, this also corresponds to increased volatility. Determining properties of these new compounds is a key consideration for engineering process design. Here, for the first time we report a comprehensive study on the vapor pressures, heat capacities, and enthalpies of vaporization of symmetric 1,3-diethers of glycerol and provide a group additivity model for estimating the enthalpies of vaporization. The properties of these glycerol-derived solvents are compared to other compounds with similar structures.
