The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid( cas:560-09-8 ) is researched.HPLC of Formula: 560-09-8.Rahman, Mohammad Arifur; Hopke, Philip K. published the article 《Mechanistic Pathway of Carbon Monoxide Off-Gassing from Wood Pellets》 about this compound( cas:560-09-8 ) in Energy & Fuels. Keywords: mechanistic pathway carbon monoxide off gassing wood pellet storage. Let’s learn more about this compound (cas:560-09-8).
The off-gassing of carbon monoxide (CO) from stored wood pellets was identified as a significant problem, potentially resulting in adverse occupational and residential exposures. The mechanism for the production of CO from wood pellets was not fully identified. A multiple step process was hypothesized. The reaction is initiated by the autoxidation of unsaturated compounds, including fatty acids and terpenes, by mol. oxygen. As a byproduct of these reactions, hydroxyl radicals are formed. Then, the bulk of CO results from the reactions of hemicellulose and hydroxyl radicals. To understand the mechanistic pathway of CO off-gassing, a number of experiments were conducted in which CO was measured and evolved organic compounds were analyzed using gas chromatog.-mass spectrometry (GC-MS). These studies identified a number of short- and long-chain aldehydes from the evolved gases that indicates the autoxidation mechanism. However, there is insufficient mass of these unsaturated compounds in wood to support the observed mass of off-gassed CO. However, autoxidation would form hydroxyl radicals. The role of hydroxyl radicals was studied using a radical scavenger, and its role in CO production was confirmed. Thus, if the autoxidation initiation can be eliminated, then CO off-gassing from pellets would be substantially reduced. Destruction of the reactive compounds with ozone led to a suppression of CO formation, suggesting an approach to process the wood fiber that would result in low or no CO emission wood pellets.
As far as I know, this compound(560-09-8)HPLC of Formula: 560-09-8 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
