Herbicidal compositions are provided which contain combinations of glyphosate (N-(phosphonomethyl)glycine) and sulfuric acid, and/or combinations of glyphosate, sulfuric acid and a chalcogen-containing compound of the formula R1 -CX-R2 wherein X is selected from oxygen and sulfur, R1 and R2 are ...
Stratospheric aerosol has long been seen as a pure mixture of sulfuric acid and water. Recent measurements, however, found a considerable carbonaceous fraction extending at least 8 km into the stratosphere. This fraction affects the aerosol optical depth (AOD) and the radiative properties, and he...
polyamide (B) having a relative viscosity of 1.0 or higher (according to JIS K6810, in 98% sulfuric acid) and 97-3pts.wt. component A is blended with a substance (C) that will generate metallic ions (e.g., magnesium acetate) in an amount sufficient for the metallic ions to ...
Corrosion inhibition, hydrogen evolution and antibacterial properties of newly synthesized organic inhibitors on 316L stainless steel alloy in acid medium Electrochemical corrosion behavior and hydrogen evolution reaction of 316L stainless steel has been investigated, in 0.5 M sulfuric acid solution contai.....
Extraction of arsenic(III) and arsenic(V) from sulfuric acid solution was studied. Cyanex 923, Cyanex 925, dialkyldithiophosphinic acids (Cyanex 301), hydr... L Iberhan,Maciej Winiewski - 《Journal of Chemical Technology & Biotechnology》 被引量: 41发表: 2003年 Kinetic study of Ce4+ extrac...
12. The FA from the total lipid extracts were converted to their methyl esters by trans esterification in methanol containing 3% concentrated sulfuric acid at 80 °C for 4 h. Methyl esters of FA were analysed in a Perkin Elmer-Clarus 500 chromatograph equipped with flame ionization detector (...
Laboratory studies of the 248 nm photooxidation of Fe(II) to Fe(III) in concentrated sulfuric acid solutions indicate that photochemical reactions in the s... GA Rowland,LF Phillips - 《Geophysical Research Letters》 被引量: 3发表: 2000年 Composition of the Venusian atmosphere after Venus Expres...

Hazelnut skin extracts or hydrolysates (1 mL in methanol) were mixed well with 2.5 mL of vanillin reagent (1% w/v vanillin in methanol) and 2.5 mL of sulfuric acid (25% v/v in methanol) and rested at room temperature for 20 min. After this period absorbance measurements were taken at ...
Under some circumstances, the sulfur trioxide combines with moisture in the boiler flue gases to produce sulfuric acid. This acid can corrode the surfaces of this eguipment. The composition offered here comprises a particulate car- rier having a relatively large surface area, and a particulate, ...
