The densities of polyethylene glycols

The densities of five polyethylene glycols (ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and pentaethylene glycol) at temperatures between 398 and 423 K were measured using a vibrating tube densitometer and are reported in this paper. The densities were correlated usi...

Description
Summary:The densities of five polyethylene glycols (ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and pentaethylene glycol) at temperatures between 398 and 423 K were measured using a vibrating tube densitometer and are reported in this paper. The densities were correlated using a modified Rackett equation and a generalized correlation was developed for the homologous series of polyethylene glycols. The correlation was verified using published data on polyethylene glycols containing up to 84 carbon atoms.
