4. strong acid pure sulfuric acid is a colorless oily liquid, while 10.4 ° c to set. When heating pure sulfuric acid, boiling point 290 ° c, and liberating part of sulfur trioxide up to acid concentration down to 98.3% point when sulfuric acid for the constant boiling solution, 338 °...
Next, the polymer is dissolved in sulfuric acid to create a liquid crystalline solution. The solution is then spun into fine, naturally yellow or dye-infused continuous filament yarns by a wet-spinning process. These fibers are completely crystalline, with molecular chains running parallel to the ...
The sulfuric acid solution is stored as a recycling methodological null exfoliation liquidPROBLEM TO BE SOLVED: To use copper or copper alloy waste from which a nickel-plating is peeled as a raw material for producing the copper or the copper alloy by peeling nickel from the copper or the ...
sulfuric acid, sulfuric also spelled sulphuric (H2SO4), also calledoil of vitriol, or hydrogen sulfate, dense, colourless, oily, corrosive liquid; one of the most commercially important of all chemicals. What is similar to sulphuric acid?
The wild-type rBxTW1 was purified by a single step of fast protein liquid chromatography using an ÄKTA Purifier system (GE Healthcare). The dialyzed crude was loaded onto a 5-mL HiTrap SPFF cartridge (GE Healthcare), equilibrated in 10 mM sodium acetate buffer (pH 4) and keeping a...
The reaction of propene and water in the liquid or gas phase, at relatively high pressures, resulting in direct hydration. This process takes place in the presence of solid acidic catalysts. The requirement of highly pure propane is present here. ...
a纯硫酸是无色、粘稠,导电性能极高的油状液体,并不易挥发,但是加热沸腾前会产生大量的白雾状硫酸酸雾。 The vitriol oil is the achromatic color, sticks thickly, the conductive energy level high oily liquid, not easy to volatilize, but in front of the heating ebullition can produce the massive whit...
The bioactive substance was further purified by liquid chromatogra- phy using size-exclusion (Fig. 1a) and C-22 reverse phase (Fig. 1b,c) columns followed by preparative thin-layer chromatography (TLC) (Fig. 1d). Analytical TLC of the sample in the final step of purifica- ...
