Líquidos iónicos y sus interesantes propiedades.

                La primera vez que escuché el término líquido iónico me llamó poderosamente la atención. Mi mente de ingeniero químico novato dispuso una típica imagen de un disolvente líquido, por ejemplo, unas siempre socorridas moléculas de agua pululando por el espacio, con iones, tanto negativos como positivos, en su seno.                ...

Molecular Weight Control in Step Growth Polymerization

Molecular Weight determines the mechanical properties of polymers as well as it affects their viscosity, therefore it is the key parameter to control in order to obtain the desired characteristics. In step growth polymerization,  the chemical equation can be described as follows: The polymer results of the addition of  two bifunctional monomers, a monomer plus a dimer, a dimer plus a trimer and so on. Thus,  the molecular...

Biorefinerías 2G

                En un anterior artículo he mencionado las nuevas tecnologías en cuanto a obtención de bioetanol que se nos vienen encima. Es decir, la producción de bioetanol a partir de compuestos de naturaleza lignocelulósica, sin necesidad de emplear alimentos como materia prima, con las indeseables consecuencias que ello conlleva. Para simplificar, me referiré...

Melamine Manufacturing Process

Melamine is a white powder organic base which is mainly used to form resins with formaldehyde (MF) and formaldehyde-urea (MUF), extensively used as coatings for furniture, textiles and paper or as plastizers. Melamine is obtained from Urea in two stages: First the urea decomposition to form isocyanic acid and ammonia, and afterwards a formation step yielding melamine and carbon dioxide. The...

Concrete and CO2

                In a world that consumes annually 3571 MTm of Portland concrete; between the 7-5% of the CO2 emissions are associated with the production of this conglomerate. Paradoxically the measures taken in the Kyoto treaty did not succeed, because of the nature of the concrete industry.                 In Europe, the emissions of CO2 are regulated by the European Union that gives the rights...

Decision Making in Design

The following text is a summary of the course 'Methods and Techniques for Design', part of the SAI program 'Process and Product Design' of TU/e, taught by Dr. Kees van Overveld in April 2014. The motivator of Research is the curiosity for valid knowledge about a determined subject, in which a single, unique and reproducible answer is attained. The progress of research is based on observation. Design however arises from the need...
