Abstract | Polyoxymethylene dimethyl ethers (PODEn) have aroused widespread industry interests due to the prospects for clean fuel additives or substitutes. The densities of liquid PODEn, were measured with an oscillation tube densimeter and fitted with the Racket equation. The self-expanding empirical density model has been developed to predict the densities of PODEn, whose pure and reliable monomer could not be readily available. The density behavior of PODE-PODE mixtures, PODE3-n-hexadecane and PODE3-tetralin blends was studied. Results showed the excess volumes of PODE-PODE are negative and approximately equal to zero, indicating PODE-PODE mixtures could be regarded as regular solution at temperatures from 273.15 to 363.15 K. While the excess molar volumes of PODE3-hexadecane and PODE3-tetralin blends are positive over the complete mole fraction range. The breaking of self-association of the PODE3 molecules by dilution effect might make a positive contribution to excess volume besides physical interactions. The densities of practical PODEn-diesel blends were estimated and results agreed well with experimental data. |
