Reversible, solid state capture of carbon dioxide by hydroxylated amidines.
Hydroxylated amidine derivatives can capture, store, and release CO(2) reversibly in the solid state in a quantitative manner under clean and dry conditions at ambient temperature.
متن کاملContinuous Synthesis of Oleyl Oleate in Supercritical Carbon Dioxide using Solid p-Toluenesulfonic Acid as Catalyst
Supercritical carbon dioxide (SC-CO2) was used as solvent to synthesize oleyl oleate as an analog of Jojoba oil from oleic acid and oleyl alcohol with high conversion (100%) of the acid into ester in a short time of 100 min. Utilizing a low cost solid catalyst, p-toluenesulfonic acid monohydrate (PTSA), the esterification reaction was performed, without any prior preparation step...
متن کاملAversiveness of carbon dioxide.
Carbon dioxide can produce aversive stimulation of the upper airways, and in their recent review Conlee et al. (2005) emphasized: ‘y Leach et al. (2002) concluded that CO2, either alone or in combination with argon, cannot be used humanely at any concentration and is therefore unacceptable as a euthanasia agent for laboratory rodents, particularly when more humane methods exist. The findings of...
متن کاملAversiveness of carbon dioxide.
We are grateful to Dr Ronald Wood for providing in his letter in the July issue (Wood 2005) his expert views and methodologies that could potentially be used in future to test the behavioural effects of airborne contaminants and irritants. Dr Wood seems to accept in his letter that carbon dioxide is aversive but he is unsure how aversive, and believes that it can be safely and humanely used in ...
متن کاملCarbon dioxide - induced
Cockroaches (Periplaneta americana) learned to passively avoid electric shock in a two-compartment box after a single training trial. However, Ss exposed to CO2 gas immediately after the training trial failed to show retention of the previous experience when tested 24 h later. Results obtained are consistent with those observed in studies of retrograde amnesia in vertebrates. Article: Numerous ...
