Determination of ethanol using flow injection enthalpimetry.
A flow injection enthalpimetric method for the determination of ethanol in fuel-grade ethanol, based on the heat of dilution of ethanol, is described. The accuracy and precision were 0.05% of ethanol; interferences by several substances are discussed. A similar procedure was also applied to the determination of ethanol in wines and spirits after distillation, yielding a precision of 0.0%0.1% of...
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...
Determination of Metal Ions in Fuel Ethanol after Preconcentra
Este trabalho descreve a síntese e caracterização da sílica gel modificada com grupos 5-amino1,3,4-tiadiazol-2-tiol (SiATT), e os resultados de um estudo de adsorção e pré-concentração (em batelada, e em fluxo utilizando-se técnica de coluna) de Cd(II), Co(II), Cu(II), Fe(III), Ni(II), Pb(II) e Zn(II) em meio etanólico. A capacidade máxima de adsorção da SiATT determinada para os íons metálicos...
متن کاملDynamic Analysis of Ethanol, Glucose, and Saccharomyces for Batch Fermentation
In this paper, a dynamic model is presented to describe the behavior of glucose concentration, Saccharomyces, and ethanol concentration during batch fermentation process. The desired product of batch alcohol fermentation is ethanol. The form of this mathematical model is nonlinear differential equation systems. The equilibrium point stability of the dynamic model is discussed. Further, simulati...
متن کاملEnzymatic determination of ethanol and glycerol by flow injection parallel multi-site detection
A flow injection method was developed for the sequential enzymatic determination of ethanol and glycerol in wines, using immobilised ethanol dehydrogenase and glycerol dehydrogenase, respectively. The enzymes were immobilised separately on alkylaminated controlled pore glass. A multi-site spectrophotometric detection system was used in parallel configuration to monitor the absorbance change in ...
