The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 2419-56-9, Name is H-Glu(OtBu)-OH, SMILES is [H][C@](N)(CCC(=O)OC(C)(C)C)C(O)=O, in an article , author is Zadshir, Mehdi, once mentioned of 2419-56-9, Recommanded Product: H-Glu(OtBu)-OH.
Self-standing films of cellulose nanofibril derivatives were prepared via oxidation by the 2,2,6,6-tetramethyl-1piperidinyloxy radical and amidation with octadecylamine (ODA). The transparency and rigidity of the films decreased and their flexibility increased as the amide/carboxyl ratio increased. The introduction of the ODA also resulted in rising contact angles of water (from 43.5 degrees to 117 degrees) and oleic acid (from 22.5 degrees to 57.1 degrees). Furthermore, the films exhibited unique oil repellency: a drop of hexadecane slipped without tailing on the surface modified by ODA. This phenomenon was observed after moderate modification (water contact angle: 95-114 degrees) and was absent for the films with the lowest and highest extents of modification. Then, the antifingerprint property of the films was examined by means of the powder test, and a reduction in fingerprints on the films was demonstrated. These results suggest the usefulness of developing transparent, self-standing oil-repellent films without per-fluorinated compounds for antifingerprint and other antifouling applications.
