The content of carbonate and its presence status in phosphate ore have large effect on acid decomposition activity of phosphate ore. 磷矿中碳酸盐的含量及在磷矿晶体中的存在状况对磷矿的酸解反应活性有着较大的影响。 www.chemyq.com 2. The results show that athletes' aerobic endurance, lactic acid ...
Carbonate decomposition of carbonic refractory gold ore and the following pressure oxidation were studied. In the carbonate decomposition procedure, the effects of liquid-to-solid ratio and reaction time on decomposition ratio of carbonate were investigated. The experimental result shows that the ...
The method was successfully applied to a range of monomer classes (for example, (meth)acrylates and (meth)acrylamides), solvents (for example, DMSO, dioxane, acetonitrile and water) and RAFT agents (for example, trithiocarbonates and dithiobenzoates) and was also compatible with conventional ...
sodium hydroxide solution and sodium carbonate solution. Acetylsalicylic acid has antipyretic analgesic, anti-inflammatory and anti-rheumatism effect, that’s why it is often used for fever, headache, muscle pain, neuralgia, rheumatic fever, acute rheumatic arthritis, gout, etc.; also it has antiplat...
Upon heating, alkali metal and alkaline earth metal oxalic acid salt can lose carbon monoxide and form carbonates with carbonate continuing to be subject to heating to be further decomposed into oxide and carbon dioxide. The oxalic acid salt of nickel, cobalt and silver can finally produce metal...

To obtain pureformic acid, the product has to split off the salt and the reaction solution. Among others, the formic acid is isolated from the catalyst, which in most cases could also catalyze the decomposition of formic acid depending on the reaction conditions. Consequently, the separation of...
°C. Stability: Aspirin decomposes rapidly in ammonium acetate, alkali metal of acetate, carbonate, citrate or hydroxide solutions. There are two crystal forms of aspirin including crystal form I and II. OccurrenceUnripe fruits and vegetables are natural sources of salicylic acid, particularly ...
It is colorless to white prismatic crystals with the relative density being 1.284 (4 ℃), the melting point being 42 ℃, the boiling point 265 ℃ (decomposition ) and 125 ℃ (2.533 × 103Pa); it is slightly soluble in water (25 ℃ when 0.937) but easily soluble in alcohol, ether ...
