Other examples of gas generating reactions are disclosed above.Any acid can be used as a reactant. However, weak acids are preferred, as they typically are safer to handle, produce less undesirable by-products, and are less reactive. Also, multifunctional acids are preferred. Multifunctional ...
In a gas phase reaction forming a normally solid product at least one reactant gas is pre-heated to 250-800 DEG C. and subsequently heated before or during the reaction to 800-2000 DEG C. by an electric discharge running at 1-10 kv., any other reactant gas(es) being introduced cold...
To mitigate the impact of surface exchange reactions, two feasible approaches can be applied: increasing the membrane thickness and improving the kinetics of surface exchange reactions with some catalytic-active agents. It is noteworthy that according to the models that are limited by the bulk ...
is pressure -and temperature-dependent. The calculated atmospheric lifetimes of CH2NH⋯H2O (~ 8 min) are too short to undergo secondary bimolecular reactions with other atmospheric species. Our results suggest that the formation of CH2O and NH3likely to occur in the combustion of biomass burnin...
Linear α-olefins, derived from light alkene oligomerization reactions, are broadly used as lubricants and co-monomers in polymer synthesis, and represent one of few examples for which homogeneous catalysts1are still employed in bulk chemical production. Transition-metal compounds selectively convert light...
Another difference with solar values is indicated by the presence ofdeuteriumon Jupiter. This heavy isotope of hydrogen has disappeared from the Sun as a result of nuclear reactions in the solar interior. Because no such reactions occur on Jupiter, the ratio of deuterium to hydrogen there should...
Landfill gas is produced by wet organic waste decomposing under anaerobic conditions in a biogas. In fact, landfill gas is a product of three processes: (1) evaporation of volatile organic compounds such as low-boiling solvents, (2) chemical reactions between waste components, and (3) microbial...
Comparison of PH3Isotherms for Zeolite 5 Å and Reactions of Lewis Acids with PH3 A series of reaction isotherms for examples 1, 3, 6, 7, and 8 were acquired for comparison to a reported isotherm for PH3adsorption onto zeolite 5 Å. The isotherms are shown in FIG. 2. ...
as illustrated in Reactions1and2. There are two principal strategies for mineral carbonation: in situ and ex-situ. The in situ strategy involves the creation of carbonates by pumping CO2into subsurface rock formations, while the ex-situ strategy refers to the generation of carbonates using pre-mi...
The thermodynamic properties of a substance are key to predicting its behavior in physical and chemical systems. Specifically, the enthalpy of formation and entropy of a substance can be used to predict whether reactions involving that substance will pro
