Exempel på hur du använder DICHLOROMETHANE i en mening

• Also, coordinating solvents, such as tetrahydrofuran and dichloromethane, can bind irreversibly to the copper catalyst, reducing its effectiveness.
• Aside from dichloromethane, some popular stripping solvents are N-methylpyrrolidone, dimethylformamide, benzyl alcohol, and dimethyl adipate.
• Hydrogen bromide reacts with dichloromethane to give bromochloromethane and dibromomethane, sequentially:.
• Common mobile phase solvents, in order of increasing polarity, include hexane, dichloromethane, ethyl acetate, acetone, and methanol.
• It is a red-brown colored solid that is soluble in hydrocarbon solvents such as benzene, and more so in tetrahydrofuran or chlorinated solvents such as dichloromethane.
• Typically, one of the phases will be aqueous, and the other a lipophilic organic solvent such as ether, MTBE, dichloromethane, chloroform, or ethyl acetate.
• The reagent Selectfluor is derived by alkylation of DABCO with dichloromethane following by treatment with fluorine.
• The reaction is much less efficient in homogeneous systems such as dichloromethane, toluene and acetonitrile or even the solvent free reaction or even the water reaction but now at 50°C.
• It is highly soluble in dichloromethane, tetrahydrofuran, acetonitrile and dimethylformamide, but insoluble in water.
• Removal of the Boc in amino acids can be accomplished with strong acids such as trifluoroacetic acid neat or in dichloromethane or with HCl in methanol.
• The cyclization of certain allyl pulegones in scheme 7 with titanium tetrachloride in dichloromethane at −78 °C gives access to the decalin skeleton with the hydroxyl group and chlorine group predominantly in cis configuration (91% cis).
• In 2009, the Taiwanese Environmental Protection Administration (EPA) found that the soil and the groundwater in the area close to Formosa Plastics' Renwu plant had been polluted by benzene, chloroform, dichloromethane, 1,1,2-Trichloroethane, 1,1-dichloroethylene, tetrachloroethylene, trichloroethylene, and vinylchloride.
• Removal of the BOC group in amino acids can be accomplished with strong acids such as trifluoroacetic acid in dichloromethane, or with HCl in methanol.
• Aprotic conditions often use an organic solvent such as acetonitrile or dichloromethane with electrolytes such as lithium perchlorate or tetrabutylammonium salts.
• Reductive opening of the ketal under modified Hunter conditions in dichloromethane yields an inseparable mixture of isomeric mesylates.
• The hydrolysis of dichlorosilane in diethyl ether, dichloromethane, or pentane gives cyclic and linear polysiloxanes.
• Cyclopropanone has been prepared by reaction of ketene with diazomethane in an unreactive solvent such as dichloromethane.
• Typically, the alcohol to be protected is deprotonated with a non-nucleophilic base such as N,N-diisopropylethylamine (DIPEA) in dichloromethane followed by addition of the chloromethyl reagent.
• For example, in solution in dichloromethane, ferrocene is oxidised to ferrocenium hexafluorophosphate:.
• According to Ogawa and Curran, trifluorotoluene is similar to dichloromethane in standard acylation, tosylation, and silylation reactions.
