In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Recommanded Product: 2-Methylbenzofuran, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 4265-25-2, name is 2-Methylbenzofuran. In an article，Which mentioned a new discovery about 4265-25-2
PVC and tobacco samples were pyrolyzed in a rotary furnace at different temperatures and reaction gas compositions. Released gaseous products were analyzed using single photon ionization (SPI)/resonance enhanced multiphoton ionization (REMPI)-time-of-flight mass spectrometry (TOFMS). These soft and selective ionization techniques allow fast and comprehensive on-line monitoring of a large variety of aliphatic and aromatic substances without fragmentation of the molecular ions. The thermal decomposition of PVC led to the appearance of chlorinated aromatic compounds at trace levels, which could be detected with SPI-TOFMS. Polycyclic aromatic hydrocarbons (PAH) were simultaneously accessible by REMPI-TOFMS. Different tobacco types can be distinguished by photoionization mass spectrometry of their gaseous pyrolysis products. In addition, pyrolysis products can be classified in three groups depending on their behaviour at different pyrolysis temperatures, which might help to unravel formation mechanisms and chemical pathways of hazardous substances.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4265-25-2, help many people in the next few years.Recommanded Product: 2-Methylbenzofuran
