Alkali-hydrolyzed lignocellulose was liquefied into polyols by acid-catalyzed dissolution, and then cross-linked with castor oil to prepare bio-based cross-linked polyurethane. Then, bis (2-hydroxyethyl) disulfide (SS) with self-healing function was used to reduce foaming in the curing process of polyurethane coating. Afterwards, disulfide bond modified crosslinked bio-based polyurethane coating (BCSPU) was applied to controlled-release urea (CRU). The results of excitation-emission matrixes indicated that SS made the coating smoother and denser and preventing the release of non-film-forming substances. Crosslinking modification technol. significantly extended the controlled release longevity of CRU by 77.3%, and the self-healing modification further prolonged the nitrogen release longevity by 61.5%. In addition, modified coating materials were non-toxic to wheat seeds and easily biodegradable in the soil. Crosslinking, self-healing modified controlled-release urea has enormous application potential in sustainable agriculture. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Computed Properties of C4H10O3).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Computed Properties of C4H10O3
