Determination of free and total glycerol in biodiesel by spot analysis
(Elsevier Science, 2020-11)
The importance of alternative fuel production has increased in the lately years, and so has the need of methods of analysis to evaluate their quality. Biodiesel fuel is a valuable substitute to petrodiesel fuel. Among the ...
Free Glycerol Sensing in Biodiesel: Automatic System Based on Sequential Enzymatic Reactions Using a Fit-for-Purpose Chemiluminescence Detection Chamber
(American Chemical Society, 2019-10)
The transesterification reaction to produce biodiesel generates a residual content of free glycerol, which may cause several problems to the engines. According to the international specification, the free glycerol determination ...
Separation Of The Glycerol-biodiesel Phases In An Ethyl Transesterification Synthetic Route Using Water
(SOC BRASILEIRA QUIMICASAO PAULO, 2015)
Flow injection analysis of free glycerol in biodiesel using a copper electrode as an amperometric detector
(ELSEVIER SCI LTDOXFORD, 2012)
The main goal of this work was to develop a simple analytical method for quantification of glycerol based on the electrocatalytic oxidation of glycerol on the copper surface adapted in a flow injection system. Under optimal ...
Glycerol combined with oils did not limit biohydrogenation of unsaturated fatty acid but reduced methane production in vitro
(Elsevier B.V., 2015-03-01)
Three runs of in vitro incubations were conducted to evaluate the effect of glycerol (0 or 150 g/kg DM) combined with three different diets: Tifton 85 hay at 850 g/kg DM without oil seeds (HWO), Tifton 85 hay + 80 g of ...
Synthesis of a deuterated standard for the quantification of 2-Arachidonoylglycerol in Caenorhabditis elegans
(Journal of Visualized Experiments, 2019-10)
This work presents a method to prepare an analytical standard to analyze 2-arachidonoyl glycerol (2-AG) qualitatively and quantitatively by liquid chromatography-electrospray Ionization-tandem mass spectrometry (LC-ESI-MS/MS). ...
In vitro fermentation parameters and biohydrogenation of vegetable oils without glycerol
(Universidade Estadual Paulista (Unesp), 2014-02-26)
Glycerol combined with vegetable oils could limit biohydrogenation and enhance the reduction in methane production without depressing digestibility and microbial population. Three in vitro incubations were conducted to ...
