Solubility of Long-Chain n-Alkanes in Heptane between 280 and 350 K

Wax phase equilibria: developing a thermodynamic model using a systematic approach

“…Both VLE and SLE binary data were used for optimising m values, with binary interaction parameters set to zero. The VLE binaries consist of C 2 or C 3 and a n-paraffin heavier than C 20 [37][38][39][40], whilst the SLE binaries consist of a low molecular weight n-paraffin (C 5 -C 12 ) and a long chain n-paraffin (C 22 -C 36 ) [41][42][43][44][45][46]. In the latter case, due to the large differences in the molecular sizes of the hydrocarbons, a pure solid may form.…”

“…Binary interaction parameters are then optimised by matching the experimental SLE data for binaries [41][42][43][44][45][46], using T c and P c calculated with the most suitable empirical correlations. When optimising binary interaction parameters, the multi-pure-solid approach for describing wax solids has been used for the same reason detailed in the above.…”

Solubility of 1,4-butanedioic acid in aqueous solutions of ethanol or 1-propanol

“…Solubility was measured by a static method [9][10][11]16]. The apparatus for the solubility measurement and the procedure are the same as those described in the literature [12].…”

“…It is a white powered crystal produced as an intermediate of the tricarboxylic acid cycle and also as one of the fermentation products of energy metabolism [6,7]. The versatile properties of 1,4-butanedioic acid make it an important ingredient in the manufacture of various specialty and commodity chemicals [8][9][10][11]. It is purified by crystallization in the final production step [12].…”

(Solid + liquid) equilibria of (nalkanes + ethyl 1,1-dimethylpropyl ether)

“…in mixtures formed by a n-paraffin and a hydrocarbon has been discussed by many authors. (3)(4)(5)(6)(7)(8) S.l.e. diagrams for the n-paraffin and n-alkanol mixtures are of great importance to the fat, cosmetic, and oil industry, as well as research.…”
