The main solvents used are acetonitrile (CH3CN), methanol (MeOH), dimethylformamide (DMF), water, N-methylpyrrolidone (NMP), dimethylsulfoxide (DMSO), dichloromethane (CH2Cl2), and also mixtures of these solvents. A supporting electrolyte solution is often added to the electrochemical system. ...
The GBL solvent systems produced porous polymers qualitatively similar to those obtained with NMP, albeit with slightly narrower pore size distributions.Theodorakopoulos, George V.Karousos, Dionysios S.Favvas, Evangelos P.Gotzias, Anastasios D....
The basic process is similar to dry-cleaning and now uses perchloroethylene (Perc) as the solvent medium rather than the traditional Stoddard solvent. During the process a small amount of water is added with the detergent system to assist in the removal of water-soluble contaminants. The ...
properties similar to those of ethyl alcohol, making it completelymisciblewithwaterandsoluble in most organicsolvents. exxonmobilchemical.com exxonmobilchemical.com 其物理化学性质和溶解特性类似于乙醇,能够完全溶解于水并与大部分有机溶剂相溶。 exxonmobilchemical.com ...
This strategy involves the usage of a high volatility co-solvent, which dilutes perovskite precursors to a lower concentration (<0.5 M) while retaining similar film quality and device performance as a high concentration (>1.4 M) solution. More than 70% of toxic waste and material cost ...
N-methyl-pyrrolidone (NMP) is a nitrogen heterocyclic compound with a series of excellent physical and chemical properties. It is non-toxic, has a high boiling point, strong polarity, low viscosity, low corrosivity, high solubility, low volatility...
phenylacetate, ethyl phenylacetate, THF, dichloromethane, nitrobenzene, NMP, DMA, DMF, DMSO, and acetonitrile. These solvents have polarity ETvalues of from 0.19 to 0.46. In this example, the capsules may also include a polymerizer, such as DGEBA. There is no polymerizer outside of the caps...
Hassan et al. (Journal of Applied Sciences Research, 5(5): pp. 515-521, 2009) mention that sulphur could be removed from straight run diesel fuel with a mixture of NMP (normal methyl pyridine), ethylene glycol, DMF (dimethyl formamide) and furfural. ...
3. The process of claim 1 or claim 2 wherein the selective solvent is NMP, phenol or furfural. 4. The process of any one of claims 1 to 3 wherein the hydrocarbon feed stream which is extracted is a lube oil, a transformer oil, an insulating oil, a mineral oil. Description...
When using NMP, the solvent is introduced near the top of the tower while the hydrocarbon feed is introduced near the bottom. In that embodiment the hydrocarbon is introduced into the tower at a temperature in the range 0° to 200° C., preferably 50 to 150° C. , while the NMP, intr...
