In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Mechanistic Pathway of Carbon Monoxide Off-Gassing from Wood Pellets, published in 2016-07-21, which mentions a compound: 560-09-8, Name is (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, Molecular C10H16O4, Quality Control of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid.
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.
This literature about this compound(560-09-8)Quality Control of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acidhas given us a lot of inspiration, and I hope that the research on this compound((1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid) can be further advanced. Maybe we can get more compounds in a similar way.
