An oxygen generator has a composition for generating oxygen and an acidic compound and/or a basic compound. The composition for generating oxygen includes an oxygen source, an ionic liquid, a metal oxide compound and/or a metal salt, and optionally a basic compound. The oxygen source is a ...
The reaction with oxygen is one of the criteria we use to distinguish between metals (these form basic oxides) and non-metals (these form acidic oxides). Uses of Oxygen The major commercial use of oxygen is in steel production.Carbonimpurities are removed from steel by reaction with oxygen to...
BOF slag usually possesses relatively high basicity (ratio of alkaline oxides to acidic oxides) and presents in different mineral phases, including tricalcium silicate (C3S), dicalcium silicate (C2S), dicalcium ferrite (C2F), MgO, CaO and RO phase (CaO, MgO, MnO and FeO solid solution) (Be...
1. Thermal decomposition of certain salts, such aspotassiumchlorate or potassium nitrate: The decomposition of potassium chlorate is catalyzed by oxides of transition metals;manganesedioxide (pyrolusite, MnO2) is frequently used. The temperature necessary to effect the evolution of oxygen is reduced from...
Boiling cell walls in water, in solutions of chelating agents or in dilute acid solubilizes a complex mixture of acidic and neutral polysaccharides known ... MC Ericson,AD Elbein,J Preiss - 《Carbohydrates Structure & Function》 被引量: 25发表: 1980年 ...
nitrogen. On the basis of extensive experimental studies, he correctly interpreted combustion and respiration as processes of the interaction of various substances and oxygen. Since oxygen in a constituent of acids, Lavoisier called itoxygène,that is, “acid former” (from the Greekoxys[acidic]) ...
To test the role of charge of the peptide, one of the basic amino acids (Arg or Lys) in each of the three basic clusters of EJ1 was substituted with an acidic amino acid (Asp; EJ10, hereafter referred to as the control peptide, CP), and this step completely ablated the effects on...
Detailed study revealed that the cation with acidic proton and basic acetate anion could simultaneously form multiple hydrogen bonds with the hydroxyl groups of the alcohols, which catalyzed the reaction very effectively. As far as we know, this is the first work to carry out this kind of ...
Acidic Gases Less Than StimulusContent And Without Erosive Gases Self-governed Room For Air Separation Plant And Far From Acidic Environment is Strongly Recommended6. Quality Control Process ETR Enigineering & Technology, clients can be sure of the quality of ETR solution. ETR uses only the be...
The nonionic surfactants are conventionally produced by condensing ethylene oxide with a hydrocarbon having a reactive hydrogen atom, e.g., a hydroxyl, carboxyl, or amido group, in the presence of an acidic or basic catalyst. Nonionic surfactants have the general formula RA(CH2 CH2 O)n H where...
