Примери за използване на ETHERS в изречение

• Ethers can again be classified into two varieties: if the organyl groups are the same on both sides of the oxygen atom, then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers.
• These properties follow from the polarizability of the divalent sulfur center, which is greater than that for oxygen in ethers.
• Some examples include: glycol ethers, organophosphate ester, polyalphaolefin, propylene glycol, and silicone oils.
• These products include detergents, thickeners, solvents, plastics, and various organic chemicals such as ethylene glycol, ethanolamines, simple and complex glycols, polyglycol ethers, and other compounds.
• Compared to the silyl ethers, silyl acetates are faster to hydrolyze, with the advantage that the released acetic acid is less aggressive.
• Also, this reaction does not favor the formation of bulky ethers like di-tertbutyl ether, due to steric hindrance and predominant formation of alkenes instead.
• Haworth began his work on simple sugars in 1915 and developed a new method for the preparation of the methyl ethers of sugars using methyl sulfate and alkali (now called Haworth methylation).
• The law HG 767/2001 applies restrictions on where and how aurolac, which it uses as a generic term for a variety of substances containing ethers, ketones, acetates, as well as methanol and toluene, can be sold.
• Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants.
• Polyoxymethylene dimethyl ethers Often abbreviated as OME3, OME4, OME5, and "OMEx" in papers where it is discussed as a Second-generation biofuel / Electrofuel.
• Polysaccharides and their derivatives: starches, cellulose or modified cellulose such as microcrystalline cellulose and cellulose ethers such as hydroxypropyl cellulose (HPC);.
• In organic synthesis, CAN is useful as an oxidant for many functional groups (alcohols, phenols, and ethers) as well as C–H bonds, especially those that are benzylic.
• Lower alcohols react to give glycol ethers which are commonly used as solvents, while longer fatty alcohols are converted to fatty alcohol ethoxylates (FAE's), which are a common form of nonionic surfactant.
• Then, in 1969, Jean-Marie Lehn discovered a class of molecules similar to crown ethers, called cryptands.
• Crown ethers are much broader than the oligomers of ethylene oxide; an important group are derived from catechol.
• Like most rivers in the UK, the chemical status changed from good to fail in 2019, due to the presence of polybrominated diphenyl ethers (PBDE) and mercury compounds, neither of which had previously been included in the assessment.
• Ecgonine, thebaine and their salts, benzylmorphine and the other ethers of morphine and their salts, except methylmorphine (codeine), ethylmorphine and their salts.
• NIS+ also manages several other types of data: NFS mounts (auto_master, auto_home), network booting and other parameters (bootparams, ethers, netmasks, netgroup, networks, protocols, rpc, services), security access (cred), aliases, and time zone.
• Grease can be removed by wiping with an appropriate solvent; ethers, methylene chloride, ethyl acetate, or hexanes work well for silicone- and hydrocarbon-based greases.
• Like most waterways in the UK, the chemical status was rated as fail in 2019, due to the presence of polybrominated diphenyl ethers (PBDE) and mercury compounds, neither of which had previously been included in the assessment.
• Like many rivers in the UK, the chemical status changed from good to fail in 2019, due to the presence of polybrominated diphenyl ethers (PBDE), perfluorooctane sulphonate (PFOS) and mercury compounds, none of which had previously been included in the assessment.
• This reality is inhabited by entities such as echoes, wisps, ethers, and nightwalkers, who have died in their sleep, doomed to wander the dreamscape forever.
• Pedersen for their efforts in discovering and determining uses of cryptands and crown ethers, thus launching the now flourishing field of supramolecular chemistry.
• Like most rivers in the UK, the chemical status changed from good to fail in 2019, due to the presence of polybrominated diphenyl ethers (PBDE) which had not previously been included in the assessment.
• The Bellus–Claisen rearrangement is the reaction of allylic ethers, amines, and thioethers with ketenes to give γ,δ-unsaturated esters, amides, and thioesters.
