One way to combat them is through the use of isosorbide as a monomer for the production of plastics. Isosorbide can be produced from biomass without the use of petroleum, is non-toxic and give plastics very favourable properties. The production of isosorbide is set by a series of sequential reactions that start with cellulose and culminating in the conversion of sorbitol to isosorbide by dehydration. This requires an acid catalyst for good results; industrially it is homogeneously catalysed in the presence of strong mineral acids. There are two major drawbacks associated with this process: the corrosion problems suffered by the equipment and the cost of separating the catalyst. This work consists of a bibliographic review of the available studies and patents on the dehydration of sorbitol, giving importance to the use of different catalysts to suggest a more beneficial process51 p.application/pdfengcc-by-nc-nd (c) Gil, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/SorbitolCatàlisi heterogèniaCatàlisi homogèniaTreballs de fi de grauSorbitolHeterogeneus catalysisHomogeneous catalysisBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
