Analysis of methyl ester suffocation using density functional theory at b3 lyp/6-31g(d) level
(Universidad Nacional Abierta y a Distancia, UNAD, 2009-08-14)
A mechanism for the sulfonation of methyl esters with sulfur trioxide is proposed herein. Reactions were studied in a falling film reactor and stability of the intermediate species verified by Density Functional Theory calculations at the B3LYP/6-31G(d) level. Mechanistic suppositions and experimental facts asserted a second order kinetic.

(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
Currently, the global trend towards sustainable development for environmental friendly products such as biosurfactants shows an excellent performance. Anionic surface active agents can be produced from renewable natural raw materials such as vegetable oils mainly derived from palm oil. Methyl ester sulfonate is an active component of highly biodegradable detergents, one advantage compared with detergents derived from ...
Multivariate Statistical Analysis: a Strategic Tool for Quality and Processes Control in Food IndustryAnálisis estadistico multivariado como herramienta Estratégica para el Control de procesos de calidad en la industria agroalimentaria
(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
The use of multivariate statistical techniques for quality and process control in the food industry has been growing significantly since the mid-seventies, as a result of the informatics revolution which facilitated the analysis of large data sets. Unlike univariate methods of data exploration, multivariate statistics uses as a major pillar the analysis of information described by three or more variables that can be ...
Estimating the Theoretical Value for LAN Network Throughput Based Power Line Communications Technology Under the Homeplug 1.0 StandardEstimación del Valor Teórico para el Throughput en Redes LAN Basadas en Tecnología Power Line Communications Bajo el Estándar Homeplug 1.0
(Universidad Nacional Abierta y a Distancia, UNAD, 2013-06-02)
Power Line Communications (PLC) refers to a group of technologies that allow to establish communication processes under the use of the grid as a physical means of transmission. The use of the grid as a physical means of transmission of information is not a new idea. Until a few years ago, the use of PLC had been limited to the implementation of solutions of control, automation and monitoring of sensors; which did not ...
Mathematical modeling of alcohol distillation columnsModelación Matemática de Columnas de Destilación Alcohólica
(Universidad Nacional Abierta y a Distancia, UNAD, 2011-04-13)
New evaluation modules are proposed to extend the scope of a modular simulator oriented to the sugar cane industry, called STA 4.0, in a way that it can be used to carry out x calculation and analysis in ethanol distilleries. Calculation modules were developed for the simulation of the columns that are combined in the distillation area. Mathematical models were supported on materials and energy balances, equilibrium ...
