The aim of this work is to report the experimental data and thermodynamic modeling phase equilibrium binary systems containing soybean olive oils with propane n-butane. Phase experiments were carried out using static synthetic method in a high-pressure variable-volume view cell temperature range from 30 70ºC varying solvent overall composition 5 98 wt%. Vapor-liquid, liquid-liquid vapor-liquid-liquid transitions observed at relatively low pressures. Peng-Robinson SAFT equations state without...
This work reports new vapor pressure data of soybean oil, castor and their fatty acid ethyl ester mixtures (FAEE) obtained from an enzyme-catalyzed reaction. Vapor measurements were carried out in a temperature range (290 to 355 K) using static method having differential transducer with precision 5 Pa. Degassing was performed inside the equilibrium cell by freezing thawing samples under moderate vacuum (about 50 kPa). For vegetable oils, values varied (0.19 2.16) kPa, whereas for FAEE...
Summary This paper reports a study of sugar cane juice carbonation and the evaluation variables effects such as pH, time temperature on industrially relevant parameters for quality juice. Three different batches were evaluated using complete two‐level factorial design with central point performed in triplicate. From results this work, it can be seen that higher sucrose concentrations lower percentage total soluble solids reducing sugars obtained clarified juices maximum values reaction (9.5,...
This work reports experimental phase equilibrium data for the ternary system involving ε-caprolactone, carbon dioxide, and dichloromethane. Such provide fundamental information to conduct polymerization reactions in supercritical dioxide medium. The experiments were performed using a variable-volume view cell over temperature range from 323.15 353.15 K different mass ratios of dichloromethane ε-caprolactone (0.5:1, 1:1, 2:1). Phase transitions vapor–liquid at bubble point (VLE-PB),...
