Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 61-90-5, Name is H-Leu-OH, SMILES is CC(C)C[C@H](N)C(O)=O, belongs to amides-buliding-blocks compound. In a document, author is Yamaguchi, Kazuki, introduce the new discover, Recommanded Product: 61-90-5.
This paper examines the mechanisms of interaction between two modifiers in asphalt binder: an amide-based bio-modifier, and natural rubber vulcanized by sulfur crosslinks. The amide-rich bio-modifier surface-activates the rubber, cleaving the disulfide bonds and leading to partial surface devulcanization. Computational modeling and laboratory experiments were used to evaluate the devulcanization mechanism and its effects. Results show that non-covalent interaction between the -NH2 site of the bio-modifier and the S-S crosslink of the rubber is stronger than with the C-S part of the rubber, which can potentially induce partial devulcanization. This phenomenon is reflected in the empirical results: a reduction in viscosity, due to devulcanization; and an increased resistance to fatigue, due to improved interaction between rubber and bitumen. This study provides an in-depth understanding of the surface devulcanization mechanism of rubber, in addition to insights into the complex devulcanization process happening inside a bio-modified mixture of rubber and asphalt binder. The results of this study help expand the knowledge of bio-modifiers and present a new approach for devulcanization.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 61-90-5 is helpful to your research. Recommanded Product: 61-90-5.
