Lignin was precipitated from the ethanol and soda black liquor in two ways: pH 5 and pH 2 in soda liquor, immediately and after 24 hours in acidified water in ethanol liquor. Characterization of apple tree pruning fibres (27.44% holocellulose, 27.32% 伪-cellulose and 26.15% lignin) was done...
Sodium and all the other alkali metals dissolve in liquid ammonia to give intense blue solutions, and at ordinary temperatures a slow reaction between sodium and ammonia occurs to form sodamide, NaNH2, and hydrogen, similar to the reaction of sodium with water to give NaOH and hydrogen. The ...
soda-lime glass, most common form of glass produced. It is composed of about 70 percent silica (silicon dioxide), 15 percent soda (sodium oxide), and 9 percent lime (calcium oxide), with much smaller amounts of various other compounds. The soda serves as a flux to lower the temperature...
In this study, a certain percentage of lignin in original bamboo kraft black liquor (BKBL) was separated, and the residual BKBL with low lignin content was expected to be fed into the alkali recovery boiler to reduce the heat transfer load of the alkali recovery boiler. With the decrease ...
The results show that with the effect of magnetic field, the interaction between ions and water weakens, the contact ion pairs increase and the solvent separated pairs decrease. Magnetic treatment leads to an increase of diffusion coefficients of cations and a decrease of an...
And get soda on the way home, I have an extra hour of work". Krista returned home after 5:00 PM. Krista's exact cause of death could not be determined since only her feet and one leg was found, but it is assumed she also died by gunshot. At 5:11 PM, Chandler created a note ...

Water glass, a compound containing sodium oxide (Na2O) and silica (silicon dioxide, SiO2) that forms a glassy solid with the very useful property of being soluble in water. Water glass is sold as solid lumps or powders or as a clear, syrupy liquid. It is
Silver, chemical element of atomic number 47, a white lustrous metal valued for its decorative beauty and electrical conductivity. Silver’s physical and chemical properties are intermediate between those of copper and gold. It is located in Group 11 of
