Thermometric Quantitative Selective Analysis of Sodium Methoxide in Methanol Industrial Solutions

چکیده
O metóxido de sódio é usado como reagente ou como catalisador em muitos processos industriais como, por exemplo, na síntese de fármacos e de biodiesel. O presente trabalho apresenta um novo e seletivo método analítico quantitativo termométrico para a determinação de metóxido de sódio em soluções de metanol na presença de íons hidróxido. Para fins de comparação com o método Karl-Fischer, os dois procedimentos foram aplicados a quatro diferentes soluções de metóxido de sódio em metanol, inclusive em presença de hidróxido de sódio, e os resultados foram comparados estatisticamente mostrando total concordância.

Selective Hydrogenation of Soybean Oil: IV. Fatty Acid Isomers Formed With Copper Catalysts
Materials Two soybean oils, partially hydrogenated (IV 119120) in a 2 liter Parr hydrogenator with laboratoryprepared catalysts containing copper (8) at 30 psi and 170 (sample A) and 200 C (sample B), respectively, were used in this investigation. Samples of each were transesterified in methanol with sodium methoxide catalyst, and the methyl esters were distilled under vacuum. Analvses of these...
متن کاملProcess Optimization of Biodiesel Production Using Alkaline Catalysts
The most commonly used method for biodiesel preparation is via transesterification of vegetable oil using alkaline catalysts. Biodiesel yield and oil conversion are affected by operating conditions including the catalyst formulation and concentration. Application of alkaline catalysts can also lead to undesired soap formation. This study evaluated the alkaline catalyst effects on biodiesel yiel...
متن کاملElectrochemical behaviour of iodide at a rotating platinum disk electrode in methanol
The oxidation of iodide at a rotaling platinum disk electrode in methanol has been studied. At low concentrations only one oxidation wave is seen, but at higher concentrations two steps are discerned. This is in accordance with the theory, assuming that the equilibrium between iodide, ttiiodide and iodine is reached fast and the oxidation of iodide to iodine occurs reversibly. only in approxima...
متن کاملQuantitative isolation of total glycosphingolipids from animal cells.
The quantitative isolation of total glycosphingolipids from crude lipid extracts without contamination from other lipid classes is described. The method consists of (a) acetylation of total lipids with pyridine and acetic anhydride, (b) separation of acetylated glycolipids from nonglycolipids on a magnesia-silica gel (Florisil) column, and (c) deacetylation of glycolipid in chloroform-methanol-...
متن کاملRapid Analysis of Starch Graft Copolymers
Starch graft copolymers are expected to become increasingly important as industrial and consumer chemicals in a large variety of end uses. Therefore, a quick and accurate analytical characterization of the graft copolymer is desirable. Vinyl side chains from starch-vinyl graft copolymers have preViously been isolated by several methods. Brockway (1) hydrolyzed the starch moiety with 1 N HCl at ...
