We found a quasi-incompressible and liquid mixture of ibuprofen, water acetone, that enables the crystallization ibuprofen particles by decreasing pressure from 15MPa to ambient (~0.1MPa). measured solubility in as function acetone/water-ratio for pressures 0.1MPa, 5.5MPa at 308K using cloud point method. Based on solubilities, binodal compositions ternary system were modelled NRTL-SAC model. T...

To better understand the solubility of multicomponent systems in supercritical CO2, an situ IR spectrophotometer coupled to a high-pressure cell was used measure aspirin, ketoprofen and carvone binary, ternary, quaternary at 333.2 K 353.2 pressures between 5–30 MPa. DSC ATR-FTIR allowed measuring melting temperature compounds optical microscopy observe phases. Aspirin formed eutectic mixture wi...

The solubility of sodium acetate in ternary solvent mixtures of water + methanol (MeOH) + acetonitrile (ACN), water + MeOH + 1-propanol (PrOH), water + PrOH + ACN, and MeOH + PrOH + ACN at 298.2 K is reported and mathematically represented using two numerical analyses (based on measured solubility data in 54 ternary mixtures containing the particular solvents in the mass fraction ranges between...

Molar excess Volumes, Vijk and speeds of sound , uijk of 2-pyrrolidinone (i) + benzene or toluene (j) + ethanol (k) ternary mixture have been measured as a function of composition at 308.15 K. The observed speeds of sound data have been utilized to determine excess isentropic compressiblities, ( E S κ )ijk of ternary (i + j + k) mixtures. Molar excess volumes, Vijk and excess isentropic compres...

The aim of this paper is to classify all monogenic ternary semigroups, up to isomorphism. We divide them to two groups: finite and infinite. We show that every infinite monogenic ternary semigroup is isomorphic to the ternary semigroup O, the odd positive integers with ordinary addition. Then we prove that all finite monogenic ternary semigroups with the same index...

Mixtures of randomly methylated cyclodextrins of various sizes have been evaluated in the rhodium-catalysed hydroformylation of higher olefins in an aqueous biphasic medium. A marked positive non-linear effect on 1-tetradecene conversion is observed when the CD molar ratio in the mixture is modified. The formation of 2:1 ternary inclusion complexes between RAME-CDs and the olefin is supposed to...

We present an improved version of an earlier Larson-type model of amphiphiles. Detailed descriptions of the algorithms are given and some situations where care must be taken are pointed out We use the model to calculate the condensation transition temperature of amphiphiles in a ternary mixture. The concentration percolation threshold and percolation critical exponent of arnphiphile clusters at...

The identification of the flux for a system of conservation laws is studied from a numerical point of view, on the specific example of chromatography. Different strategies to compute the exact gradient of the discretized optimization problem are developed and compared. Numerical evidence of the convergence of the method is also given in the scalar and binary case. Finally a ternary mixture with...

The τ-boride Ni(23-x)Bi(x)B(6) [x = 2.44 (1)] adopts a ternary variant of the cubic Cr(23)C(6)-type structure, with Ni(8) cubes and Ni(12) cubocta-hedra arranged in a NaCl-type pattern. Two of the four independent metal sites (8c, 3m symmetry; 4a, mm symmetry) are occupied by a mixture of Ni and Bi atoms in a 0.106 (6):0.894 (6) and a 0.350 (7):0.650 (7) ratio, respectively.

In the present paper the heat exchange performance of a counter flow double-tube condenser for a ternary refrigerant mixture R407C, composed ofHFC32/HFC125/HFC134a, is calculated using a prediction method developed by the present authors. The axial distributions of vapor and liquid bulk mass fraction, temperature, heat flux, mass flux, etc., are obtained for both a smooth tube and a microfin tu...
