Exempel på hur du använder DIMETHYLFORMAMIDE i en mening

• Note: Acetylene cylinders contain an inert packing material, which may be agamassan, and are filled with a solvent such as acetone or dimethylformamide.
• Aside from dichloromethane, some popular stripping solvents are N-methylpyrrolidone, dimethylformamide, benzyl alcohol, and dimethyl adipate.
• Solvents with higher boiling points such as water (100 °C at standard atmospheric pressure, 760 torr or 1 bar), dimethylformamide (DMF, 153 °C at the same), or dimethyl sulfoxide (DMSO, 189 °C at the same), can also be evaporated if the unit's vacuum system is capable of sufficiently low pressure.
• CYP2E1 enzyme metabolizes mostly small, polar molecules, including toxic laboratory chemicals such as dimethylformamide, aniline, and halogenated hydrocarbons (see table below).
• In the synthesis, triphenylphosphine serves as both a ligand and a reductant, and the carbonyl ligand is derived by decomposition of dimethylformamide, probably via a deinsertion of an intermediate Ir-C(O)H species.
• It is highly soluble in dichloromethane, tetrahydrofuran, acetonitrile and dimethylformamide, but insoluble in water.
• Upon addition of a N,N-disubstituted formamide (such as dimethylformamide) a hemiaminal is formed, which can easily be hydrolyzed into the desired aldehyde.
• Traditionally, these reactions require high-boiling, polar solvents such as N-methylpyrrolidone, nitrobenzene, or dimethylformamide and high temperatures (often in excess of 210 °C) with stoichiometric amounts of copper.
• In the initial enamine formation, dimethylamine (a gas) is displaced by pyrrolidine from the dimethylformamide dimethylacetal, producing a more reactive reagent.
• It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.
• The original Hajos-Parrish procedure begins with an achiral triketone in dimethylformamide and 3% (molar) catalytic (S)(−)proline.
• Acetylene is shipped and stored in metal cylinders filled with agamassan, which is half-filled with dimethylformamide (DMF) or acetone.
• The catalyst 2,2'-Azobis(2-methylpropionitrile), with the solvents dimethylformamide, dimethylacetamide, dimethylsulfoxide and dimethylsulphone were detected in the sea waters of the affected area.
• It can be used as a polar aprotic solvent, with better hydrocarbon solubility than other amide solvents such as dimethylformamide (DMF).
• Besides water (hydrothermal synthesis), solvothermal syntheses make use of a large range of solvents, including ammonia, carbon dioxide, dimethylformamide, and various alcohols such as methanol, or glycols such as hexane-1,6-diol.
• It reacts with petrolatum, nitromethane, acetonitrile, dimethylformamide, and over 25° with carbon tetrachloride.
• Almost anhydrous electrolytes based on organic solvents, such as dimethylformamide (DMF), dimethylacetamide (DMA), or γ-butyrolactone (GBL).
• Therefore, also syntheses of the much better processible salts N,N,N′,N′-tetramethylformamidinium methylsulfate (from the dimethylformamide–dimethylsulfate complex) and of N,N,N′,N′-tetramethylformamidinium p-toluenesulfonate (from dimethylformamide and p-toluenesulfonyl chloride) were investigated.
• They react with phosgene and dimethylformamide (which forms in-situ the Vilsmeier reagent) in 68% yield to 3-ethoxypropenylidene dimethylammonium chloride, an enol ether iminium salt.
• In the second method, boron nitride and graphite powder are dissolved in isopropanol and dimethylformamide, respectively, and then sonicated.
