Download or read book Determining the Quality of Novel Polyols Using Potentiometric Analysis for Biodegradable Thermoplastic Polyurethanes TPUs written by Miheer Modi and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel bio polyols made from different combinations of diacids, and diols were tested using potentiometric titrations to determine their hydroxyl number, total acid content and water content. These tests were in part accomplished by designing novel titration methods involving solvent substitutions which were verified to generate results within ±2%. The second half of this thesis focused on the synthesis of a novel polyol made from Botryococcus braunii using hydroboration-oxidation and epoxidation. Potentiometric analysis showed that the hydroboration-oxidation route was 13% more effective and supported by H NMR and FT-IR analysis. Future avenues with biodegradable adhesives could be explored.

Download or read book Analytical Techniques and Methods for Biomass written by Sílvio Vaz Jr. and published by Springer. This book was released on 2016-10-27 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the application of techniques and methods of chemical analysis for the study of biomass and its conversion processes, aiming to fill the current gap in the book literature on the subject. The use of various techniques and analytical methods is presented and discussed in a straightforward manner, providing the reader with the possibility of choosing the most appropriate methodologies for analysis of the major classes of plant biomass and its products. In the present volume, a select group of international specialists describes different approaches to understand the biomass structure, their physical and chemical properties, the parameters of conversion processes, the products and by-products formation and quantification, quality parameters, etc. Modern chemistry plays a strong economic role in industrial activities based on biomass, with an increasing trend of the importance of its application from the deployment of biorefineries and the principles of green chemistry, which make use of the potential of biomass with decreasing impact negative environmental. In this context, analytical chemistry can contribute significantly to the supply chains of biomass, be it plant or animal origin; however, with the first offering the greatest challenges and the greatest opportunity for technical, scientific and economic progress, given its diversified chemical constitution. Thus, the chemical analysis can be used to examine the composition for characterizing physicochemical properties and to monitor their conversion processes, in order to obtain better products and uses of biomass. The quality of the biomass used determines the product quality. Therefore, reliable information is required about the chemical composition of the biomass to establish the best use (e.g., most suitable conversion process and its conditions), which will influence harvest and preparation steps. Conversion processes should be monitored for their yield, integrity, safety, and environmental impact. Effluent or residues should be monitored and analyzed for environmental control. Co-products need to be monitored to avoid interference with the product yield and product purity; however, co-products are also a good opportunity to add value to the biomass chain. Finally, products need to be monitored and analyzed to determine their yields and purity and to ensure their quality. In this context, analytical chemistry can contribute significantly to the biomass supply chains, be it of plant or animal origin.
