Super hygroscopic polymer films composed of biomass and hygroscopic salts are able to condense moisture from atmospheric humidity. [16] By implementing rapid sorption-desorption kinetics and operating 14–24 cycles per day, this technique produced an equivalent water yield of 5.8–13.3 L kg −1 of sustainable raw materials, demonstrating the ...
[1] Its p K a value in water cannot be accurately determined but in acetonitrile it has been estimated as −0.10 and in 1,2-dichloroethane −12.3 (relative to the p K a value of 2,4,6-trinitrophenol ( picric acid ), anchored to zero to crudely approximate the aqueous p K a scale [ 2 ] ), making it more acidic than triflic acid (p K a MeCN = 0 ...
Primary efflorescence is named such, as it typically occurs during the initial cure of a cementitious product. It often occurs on masonry construction, particularly brick, as well as some firestop mortars, when water moving through a wall or other structure, or water being driven out as a result of the heat of hydration as cement stone is being formed, brings salts to the surface that are not ...
The second largest application of calcium chloride exploits its hygroscopic nature and the tackiness of its hydrates; calcium chloride is highly hygroscopic and its hydration is an exothermic process. A concentrated solution keeps a liquid layer on the surface of dirt roads, which suppresses the formation of dust. It keeps the finer dust ...
Cgingold 04:04, 1 November 2006 (UTC) I have added a reference to the list of hygroscopic substances which looks to be the source of most of the original list. I have removed Diesel Fuel from the list of hygroscopic substances. Disel Fuel as per ASTM standard is allowed 200mg water per 1kg of fuel [1]. This is a tiny amount, indeed large ...
