Yang, Yun et al. published their research in Organohalogen Compounds in 1997 | CAS: 205-39-0

Naphtho[2,1-b]benzofuran (cas: 205-39-0) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antiviral, antimicrobial, antitumor, anti-inflammatory.Recommanded Product: 205-39-0

Distribution of oxygenated and unoxygenated aromatics from phenol pyrolysis at low temperatures was written by Yang, Yun;Mulholland, James A.. And the article was included in Organohalogen Compounds in 1997.Recommanded Product: 205-39-0 This article mentions the following:

The gas-phase pyrolysis of phenol was studied to investigate the effect of temperature on the distribution of aromatic products in waste incineration. Experiments were conducted in a flow tube reactor at 400-700° with a residence time of 20 s. Oxygenated and unoxygenated aromatic products were detected. The major oxygenated product was dibenzofuran which peaked at 650°. The major unoxygenated products were benzene, naphthalene, and indene. Yields of these and higher mol. weight polyaromatic hydrocarbons increased with temperature The conversion rate of phenol was <5% at <550°, but >95% at ≥650°. In the experiment, the researchers used many compounds, for example, Naphtho[2,1-b]benzofuran (cas: 205-39-0Recommanded Product: 205-39-0).
