Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 586-77-6, Name is 4-Bromo-N,N-dimethylaniline, SMILES is C1=C(N(C)C)C=CC(=C1)Br, belongs to bromides-buliding-blocks compound. In a document, author is Courbon, Emilie, introduce the new discover, Name: 4-Bromo-N,N-dimethylaniline.
New prominent lithium bromide-based composites for thermal energy storage
Four different LiBr-based composite materials have been synthesized with silica gel or activated carbon as host porous matrix. High salt contents were incorporated in these composites: 37 wt% and 53 wt% for silica gel/LiBr composites; 32 wt% and 42 wt% for activated carbon/LiBr composites. The performance of these materials in conditions representative of the applications of sanitary hot water production and space heating demonstrates the very high potential of the silica gel/LiBr 53 wt% composite. It exhibits an unprecedented energy storage density of 261 kWh/m(3) (adsorption temperature: 30 degrees C, desorption temperature: 80 degrees C and water vapor pressure of 12.5 mbar) and of 381 kWh/m(3) when the desorption temperature reaches 120 degrees C. This promising material presents a good composition homogeneity, high water uptakes between 10 degrees C and 80 degrees C, and no measurable loss of sorption properties upon 10 cycles. This composite was tested in an open type laboratory set-up to complete its analysis for heat storage applications, at the scale of 200 g. The best energy storage density reached during 3 h 26 min was as high as 246 kWh/m(3) (adsorption temperature: similar to 29 degrees C and water vapor pressure of similar to 12.5 mbar).
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 586-77-6 is helpful to your research. Name: 4-Bromo-N,N-dimethylaniline.
