Potassium trifluoromethanesulfonate is a kind of organometallic compound, which can be used to study the mixed alkali effect and short-range interaction in polyepoxyethane electrolyte and the electrochemical behavior of glass carbon in super acid medium. The purity of potassium trifluoromethanesulfonate can be obtained by detecting the ion of trifluoromethanesulfonate by ion chromatography, which provides monitoring…
Ionic liquid is a kind of molten salt which is completely composed of ions, and now it mostly refers to molten salt in liquid state when the temperature is lower than 100℃. It have the following characteristics: small vapor pressure, non flammable, good stability, large heat capacity, good conductivity, with “designability”, and special solubility for…
Polyethylene glycol (PEG) is the general term of glycol polymers, including PEG300, PEG400, PEG600,PEG1000, PEG4000, PEG6000, PEG10000, PEG20000 (PEG20M), etc. With the increase of average molecular weight, the physical state of PEG changes from liquid to paste or wax solid at room temperature. All kinds of PEG have good water solubility, organic solvent solubility and…
Sulfolane (also known as Tetrahydrothiophene sulfone) has stable chemical properties, and generally does not polymerize or decompose under acid and alkali conditions. Therefore, sulfolane is used as an ideal solvent for aromatics extraction. But in the process of industrial application, sulfolane will continue to deteriorate. The reason of degradation is not very clear, but the…
Cyclopentanone is a colorless liquid, which is miscible with alcohol and ether, insoluble in water, and has mint aroma. It is an important intermediate of pharmaceutical and pesticide fine chemical products. The ion content of Cyclopentanone will affect its performance and quality, so it needs to be detected and monitored. Download PDF
Plastics, micro- and nanoplastics pollution in oceans, lakes and other water sources is a well-documented issue. Uptake of these particles by shellfish and fish is one avenue for the pollutants to enter the food chain and cause possible adverse effects. Microand nanoplastics are commonly used in commercially available products as abrasives. They end up in…
