Isobaric vapor-Liquid Equilibrium of Ethyl-Acetate+ 2-Propanol and Ethyl Acetate+ Ethanol Mixtures at 84.8 kPa
Accurate vapor-liquid equilibrium data have been obtained for ethyl acetate + 2-propanol and ethyl acetate + ethanol mixtures at 84.8 kPa, and the results are discussed thermodynamically. The vapor-liquid equilibrium data are correlated with redlich-Kister, Margules, Van-Laar and Ortega, equations the parameters and standard deviation of which are calculated and reported. The best correlati...
متن کاملEffect of Inorganic Salts on the Isobaric Vapor−Liquid Equilibrium of the Ethyl Acetate−Ethanol System
The effect of various salts such as magnesium nitrate, calcium nitrate, zinc nitrate, and magnesium chloride on vapor−liquid equilibrium (VLE) of the ethyl acetate−ethanol system was studied experimentally in a modified Othmer still at atmospheric pressure. The influence of cation and anion of the salts on the VLE of the ethyl acetate− ethanol system was examined. It was observed that the order...
متن کاملThermodynamics of nitroaromatic compound adsorption from water by smectite clay.
Nitroaromatic compounds enter the environment through their use as explosives, pesticides, solvents, and synthetic intermediates in the manufacturing of dyes, perfumes, and drugs. Recent studies have found that many nitroaromatic compounds are strongly retained by smectites, especially K+-saturated smectites. Sorption occurs when nitroaromatic compounds replace water associated with the clay an...
متن کاملInfluence of the Sodium Acetate on the Vapor- Liquid Equilibrium of the System Water- Ethanol at Normal Pressure
RESUMO – This work aimed the evaluation of a saline extractive distillation for the ethanol production. Unlike the current method of dehydration of ethanol, which uses a solvent, distillation with the use of salt does not include problems related to toxicity and has lower power consumption, since salt is not volatilized within the distillation column. Many salts had been tested like calcium chl...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
