Catalytic conversion of cellulose to levulinic acid by metal chlorides.
The catalytic performance of various metal chlorides in the conversion of cellulose to levulinic acid in liquid water at high temperatures was investigated. The effects of reaction parameters on the yield of levulinic acid were also explored. The results showed that alkali and alkaline earth metal chlorides were not effective in conversion of cellulose, while transition metal chlorides, especia...
متن کاملLevulinic acid
THE TITLE COMPOUND (SYSTEMATIC NAME 4-oxo-penta-noic acid), C5H8O3, is close to planar (r.m.s. deviation = 0.0762 Å). In the crystal, the mol-ecules inter-act via O-H⋯O hydrogen bonds in which the hy-droxy O atoms act as donors and the ketone O atoms in adjacent mol-ecules as acceptors, forming C(7) chains along [20-1].
متن کاملHydrochloric Acid-Catalyzed Levulinic Acid Formation from Cellulose: Data and Kinetic Model to Maximize Yields
In this study, the kinetics of the acid catalyzed hydrolysis of microcrystalline cellulose (Avicel PH101) to levulinic (LA) and formic (FA) acids was investigated in a batch reactor over the following range of conditions: 160–200 C, hydrochloric acid concentrations of 0.309–0.927 M (11.3–33.8 g/l), cellulose concentrations of 49.8–149 mM (8.06–24.1 g/l), and residence times of 0–50 min. The max...
متن کاملSulfamic acid: A green and efficient catalyst for synthesis of mono-, bis-, and spiro- perimidines
Mild and applicable synthesis of mono-, bis-, and spiro- perimidines is demonstrated in high yields via the condensation of 1,8-diaminonaphthalene and aldehydes or ketones in the presence of sulfamic acid as a green and highly efficient catalyst. This environmentally benign and clean synthetic pathway offers several advantages, such as high yields, short reaction times and easy work-up procedure.
