Sources of carbon dioxide formed during coal pyrolysis was written by Chatterjee, Kuntal;Bal, Balkrishna;Stock, Leon M.;Zabransky, Robert F.. And the article was included in Energy & Fuels in 1989.SDS of cas: 57293-19-3 This article mentions the following:
The CO2 yield in coal pyrolysis is not uniquely dependent on the concentration of carboxyl groups in the coal. Other O-containing functional groups or coal mineral matter contribute to CO2 formation. These conclusions are drawn from the results from pyrolysis of Wyodak and Illinois Number 6 coals that were modified by removal of carboxylic acids or by the incorporation of aliphatic or aromatic esters or aromatic methoxy groups. The coals were selectively O-alkylated. In the experiment, the researchers used many compounds, for example, 1-(3-Bromopropyl)-4-methoxybenzene (cas: 57293-19-3SDS of cas: 57293-19-3).
1-(3-Bromopropyl)-4-methoxybenzene (cas: 57293-19-3) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.SDS of cas: 57293-19-3
