FPWOS). Results of this experiment revealed that TS has increased the wheat grain yield significantly (20%) through conservation of soil moisture contents (16 %) and soil fertility level. TS had decreased the gullies/rills formation through the efficient removal of excess rainwater.
Thermal and oxidative degradation of monoethanolamine (MEA) represents a major problem for modern day carbon capture technologies. Here, we report on a series of density functional theory (DFT) calculations investigating the possible chemical pathways leading to the formation of the most commonly observed degradation products. 2-Oxyzolidinone (OZD) can be formed from ring closure reactions of carbamates, carbamic acids, or isocyanates. The latter, itself, formed by dehydration of MEA. N-(2hydroxethyl)ethylenediamine (HEEDA), 1-(2-hydroxyethyl)imidazolidone (HEIA), and N-(2-aminoethyl)-N′-(2-hydroxyethyl)imidazolidin-2-one (AHEIA) are all hypothesized to form favorably from degradation reactions of OZD.MEA can undergo oxidative degradation to form imines and hydroperoxides. This work details the mechanistic steps leading to the formation of these species that could help in the location of new compounds that aim to prevent their formation in future systems. Moreover, the thermochemical data will aid in the construction of a chemical kinetic mechanism to rationalize the rate of formation of all the species in real systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
