Durante las últimas décadas, los investigadores han dirigido sus&#13;
esfuerzos hacia la protección del medio ambiente y al desarrollo de procesos&#13;
sostenibles con el entorno [1,2]. Uno de los procesos en los que se han&#13;
producido avances importantes es la síntesis de biocombustibles (biogás,&#13;
biodiesel,…). En este sentido, el uso de la biomasa como fuente de energía no&#13;
sólo satisface la necesidad energética sino que también proporciona una serie&#13;
de compuestos químicos funcionalizados, que pueden ser empleados como&#13;
punto de partida para multitud de procesos [1,3-6]. Con esta premisa,&#13;
investigadores del Pacific Northwest National Laboratory (USA) y del&#13;
National Renewable Energy Laboratory (USA) publicaron un informe en el&#13;
que se analizaban posibles compuestos de partida (building blocks o platform&#13;
molecules) para el desarrollo de una química basada en la biomasa, que&#13;
emplearía estos compuestos fácilmente transformables en otros productos de&#13;
alto valor añadido [5,6]. El glicerol (1,2,3-propanotriol) ha sido identificado&#13;
como una de las 12 moléculas de partida derivadas de la biomasa que pueden&#13;
ser convertidas en productos químicos o materiales de alto valor añadido [1,4-&#13;
7].&#13;
El glicerol se encuentra en la biomasa utilizada como materia prima&#13;
para la obtención de biodiesel en forma de ésteres de ácidos grasos o&#13;
triglicéridos, provenientes principalmente de aceites vegetales [8]. La&#13;
obtención del biodiesel se realiza vía hidrólisis o metanolisis de los...</dim:field>

Over the last few decades, researchers have directed their efforts&#13;
toward environmental protection and the development of sustainable&#13;
processes [1,2]. This approach has led to major advances in some processes&#13;
such as biofuels synthesis (biogas, biodiesel, ...). The use of biomass as an&#13;
energy source not only supply an energetic demand but also provides a wide&#13;
range of functionalized chemical compounds that can be used as a starting&#13;
point for many processes [1,3-6]. Considering all these possibilities,&#13;
researchers from both the Pacific Northwest National Laboratory (USA) and&#13;
the National Renewable Energy Laboratory (USA) published a report&#13;
including the most promising starting compounds (building blocks or platform&#13;
molecules) for the development of a biomass based chemistry, with biomass&#13;
as a renewable source of these building blocks that can be easily transformed&#13;
into other products with high added value [5.6]. Glycerol has been identified&#13;
as one of the 12 proposed starting molecules derived from biomass that can be&#13;
converted into other added-value chemicals [1,4-7].&#13;
Glycerol can be found in the vegetable oils used as raw material for&#13;
biodiesel, mainly as fatty acid esters or triglycerides [8]. Biodiesel production&#13;
is carried out via hydrolysis or methanolysis of triglycerides [9], reaching a&#13;
ratio of 10 kg of glycerol as by-product per 100 kg of biodiesel in biorefinery.&#13;
Many different chemical processes have been described for the valorisation of&#13;
glycerol, such as aqueous phase reforming, polymerization, fermentation,...</dim:field>
