Modelling methanol recovery in wine distillation stills with packing columnsFOOD CONTROLFOOD CONTROL
(ELSEVIER SCI LTD, 2011)
A simple method for simultaneous determination of acetaldehyde, acetone, methanol, and ethanol in the atmosphere and natural waters
(Royal Soc Chemistry, 2017-05-21)
Although there has been a dramatic increase in the use of ethanol fuel in several countries, there is a great lack of data related to the abundance of this alcohol and associated species in the atmosphere and in natural ...
Analysis of a two-step, noncatalytic, supercritical biodiesel production process with heat recovery
(American Chemical Society, 2007-01)
A two-step, noncatalytic process for the production of biodiesel is analyzed. The reaction of transesterification of triglycerides with methanol is carried out in supercritical conditions by adopting reaction temperatures ...
Study of an energy-integrated biodiesel production process using supercritical methanol and a low-cost feedstock
(Elsevier Science, 2015-08)
The supercritical biodiesel production process has some disadvantages such as: high reaction temperature,large molar methanol-to-oil ratios (R) and large energy consumption. To mitigate these problems, an energy integrated ...
Deacidification of vegetable oil by extraction with solvent recovery
(Springer, 2019-04)
Deacidification of a vegetable oil by extraction and regeneration of the solvent by means of adsorption was studied. This novel approach to solvent regeneration is posed as an alternative to distillation in systems with ...
Development and validation of HPLC method for quantitative analysis of triamcinolone in biodegradable microparticles
(2006-12-01)
A simple, rapid, selective and specific high performance liquid chromatographic (HPLC) method for quantitative analysis of the triamcinolone in polylactide-co-glycolide acid (PLGA) microparticles was developed. The ...

Screening method for rapid determination of polychlorinated biphenyls in transformer oil by liquid-liquid extraction and gas chromatography-mass spectrometry
(SOC BRASILEIRA QUIMICA, 2007)
A rapid and simple method was developed for screening polychlorinated biphenyls in transformer oil. The method is based on liquid-liquid extraction in methanol and subsequent direct gas chromatography-mass spectrometric ...
