A Green Method for Determination of Acid Number of Biodiesel
Neste trabalho é proposto um método simples e verde para a determinação do índice de acidez do biodiesel. A amostra é dissolvida em solução 1:1 v/v etanol:água, evitando a mistura tolueno:isopropanol:água (1:0,95:0,5 v/v/v) usada nas normas atuais. A titulação é realizada com uma solução aquosa de NaOH 0,02 mol L. O método foi comparado com o da ABNT NBR 14448, que é similar ao do ASTM D 664 e ...
متن کاملSimplification of the ASTM D3606 Method for the Determination of Benzene and Toluene in Gasoline
Benzene is used as an additive into gasoline to increase octane rating and prevent engine knocking. Being a toxic air pollutant known to have carcinogenic effects, knowledge of its concentration can be of aid in the assessment of possible health hazards to persons handling and using gasoline. The U.S. Federal Clean Air Act and the European Community specifications mandate a level of benzene in ...
متن کاملNew Rapid Method for the Determination of Total Acid Number (Tan) of Bio-Oils
Fast pyrolysis oils are one source of renewable liquid fuels, which could be used as green fuels in a sustainable manner. The ASTM D664 method used to determine the acidic constituents in petroleum products, lubricants, and biodiesel requires mixtures of isopropyl alcohol (IPA) and toluene as solvent. The ASTM method also uses large quantities of solvents for the total acid number (TAN) determi...
متن کاملAnalysis of Denatured Fuel Ethanol using ASTM Method D5501-09
Denatured fuel ethanol is the feedstock used to make different types of high ethanol content motor fuels. Before it can be used, the amount of ethanol and methanol must be measured to assure product quality. ASTM method D5501-09 uses high resolution gas chromatography to perform this analysis. In this paper, the Agilent 7890A GC system was configured to run D5501-09. Excellent system performanc...
متن کاملTHE DETERMINATION OF URINARY 17-TRIOXYSTEROIDS* BY RAYMOND RIVOIRE,t
The color reaction characteristic of cortisone and related compounds (with the 17,21-dihydroxy-20-keto grouping), which Porter and Silber (1) reported in 1950, has been used by a number of investigators to measure the “cortisone-like” metabolites of urine. To facilitate expression, we propose to give to the methods of analysis utilizing this reaction the term of “determination of 17-trioxystero...
