Rodriguez-Donis, Ivonne published the artcileModelling and experimental validation of dimethyl carbonate solvent recovery from an aroma mixture by batch distillation, SDS of cas: 140-11-4, the main research area is aroma mixture dimethyl carbonate solvent recovery batch distillation.
Modeling and exptl. validation of solvent recovery from an aroma mixture by batch distillation process is presented, with particular emphasis of the effect of the prediction of the physicochem. properties and the phase equilibrium data on the content of the aroma compounds in the distillate cuts. The illustrative case study refers to an industrial batch distillation to recover di-Me carbonate (DMC) from an extract generated by a solvent extraction process involving variable natural raw materials for tailored perfume and fragrance applications. Due to the high number of aroma compounds in natural extracts, a synthetic mixture containing six target aroma compounds (α-pinene, eucalyptol, linalool, cis-3-hexenol, fenchone and benzyl acetate) was mixed with DMC for the modeling and exptl. studies of the batch distillation process. The methodol. is tested through the simulation of the process with BatchColumn software. As physicochem. properties of the aroma compounds and the vapor-liquid equilibrium (VLE) of all involved mixtures are required for simulation study, group contribution methods are used to predict missing properties such as vapor pressure, vaporisation enthalpy and liquid and vapor heat capacities. Simulation results are in good agreement with experiments carried out in a fully automated batch distillation column at 15 kPa and help optimize the industrial process operation. The proposed methodol. can be applied for the design of other solvent recovery process in fragrance industry.
