Related Products of 591-12-8. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about Mechanism research on catalytic pyrolysis of sulfated polysaccharide using ZSM-5 catalysts by Py-GC/MS and density functional theory studies.
The mechanisms of primary product formation on catalytic pyrolysis of seaweed sulfated polysaccharide with ZSM-5 were examined in detail by using Py-GC/MS anal. and subsequent d. functional theory. Results showed that furfurals were the main product (50.3%) in bio-oil during the catalytic pyrolysis of sulfated polysaccharides. Furfural (9.1%), 5-(Hydroxymethyl)-2(5 H)-furanone (3.1%) and acetone (3.2%) were defined as typical products of Glucuronic acid unit. 5-Me furfural (41.2%), 5-methyl-2(3 H)-Furanone (0.5%) and 5-Me furan (5.4%) can be converted from rhamnose unit. The subsequent d. functional theory calculation indicated that the catalytic pyrolysis of sulfated polysaccharides by ZSM-5 catalyst could boost the pyrolysis and upgrade the bio-oil quality since the promotion of hydrodeoxygenation on catalytic reactions and ZSM-5 could promote the formation of 5-Me furfural. The hydrogen bonding and van der Waals force interactions improved the pyrolysis pathways and decreased the energy barrier, which promoted the pyrolysis. This study confirmed that ZSM-5 had a catalytic influence on pyrolysis of sulfated polysaccharides through theor. and exptl. anal., which is helpful to understand the formation mechanism of seaweed catalytic pyrolysis products.
