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 ...
Review: equipment for anionic surfactant manufacture from oil palmRevisión: Maquinaria usada para la elaboración de surfactantes aniónicos derivados del aceite de palma
(Universidad Nacional Abierta y a Distancia, UNAD, 2010-05-08)
In the present study is performed a review of the current processes of sulfonation of various raw materials for determine the process conditions in order to present the state of the art of sulfonation processes for the manufacture of anionic surfactants. There has been a scientific literature with emphasis on several aspects: Technology, sulfonation reactors and operating conditions in the process, analytical techniques ...
