Exempel på hur man kan använda DIMETHYL i en mening

• Of the volatile by-products, dimethyl sulfide has a strong, pervasive odour and carbon monoxide is acutely toxic, so the reaction and the work-up needs to be performed in a fume hood.
• Bacteria in environments both with and without oxygen can also convert methanethiol to dimethyl sulfide (DMS), although most DMS in surface seawater is produced by a separate pathway.
• For example, ethyl comes before dihydroxy or dimethyl, as the "e" in "ethyl" precedes the "h" in "dihydroxy" and the "m" in "dimethyl" alphabetically.
• Deuterated DMSO, an isotopologue of dimethyl sulfoxide used as a solvent in Nuclear Magnetic Resonance spectroscopy.
• Industrially, however, malonic acid is produced by hydrolysis of dimethyl malonate or diethyl malonate.
• 190 liters of dimethyl methylphosphonate, a CWC schedule 2 chemical used in the synthesis of sarin nerve gas, was discovered in the cargo of El Al Flight 1862 after it crashed in 1992 en route to Tel Aviv.
• Alternatively, the compound Cytochalasin D, dissolved in dimethyl sulfoxide, can be employed to achieve a similar effect by disrupting the actin microfilaments responsible for facilitating cytoplasmic movement.
• Cyclopropene can also be obtained in about 1% yield by thermolysis of the adduct of cycloheptatriene and dimethyl acetylenedicarboxylate.
• Polyoxymethylene dimethyl ethers Often abbreviated as OME3, OME4, OME5, and "OMEx" in papers where it is discussed as a Second-generation biofuel / Electrofuel.
• Aside from dichloromethane, some popular stripping solvents are N-methylpyrrolidone, dimethylformamide, benzyl alcohol, and dimethyl adipate.
• Oxidation of dimethyl sulfoxide produces the sulfone, both under laboratory conditions and metabolically.
• 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.
• The nitro group of dimethyl 4-nitropimelate (1) is reduced by palladium-catalysed hydrogenation to an amino group, which cyclises to give a mixture of the lactam ester (2) and its corresponding acid (3).
• On the other hand, dipolar aprotic solvents such as dimethyl sulfoxide and acetone are soft solvents with a preference for solvating large anions and soft bases.
• There is no consensus yet on optimal procedures for these cord blood cells, although many cryopreservation strategies suggest using dimethyl sulfoxide (DMSO), slow or controlled rate cooling, and rapid thawing.
• It may be prepared by the methylation of 1,8-diaminonaphthalene with iodomethane or dimethyl sulfate.
• However, there are many MAPP substitutes on the market, often labeled "MAPP" but containing mostly propylene with some propane and in some cases also dimethyl ether.
• Fluoromethane (originally called "fluorohydrate of methylene") became the first organofluorine compound to be discovered when it was synthesized by French chemists Jean-Baptiste Dumas and Eugène-Melchior Péligot in 1835 by distilling dimethyl sulfate with potassium fluoride.
• One method produces an enaminone by the reaction of 2-acetylpyridine with N,N-dimethylformamide dimethyl acetal.
• Ivory dishwashing liquid contains water, sodium lauryl sulfate, sodium laureth sulfate, alkyl dimethyl amine oxide, sodium chloride, PPG-26, cyclohexanediamine, phenoxyethanol, methylisothiazolinone, and fragrance.
