Dimethoxyethane is also a good solvent for oligo- and polysaccharides. Sodium naphthalide dissolved in dimethoxyethane is used as a PTFE etching solution that removes fluorine atoms from the surface, which get replaced by oxygen, hydrogen, and water. This physically etches the surface as well to prepare the surface for better adhesion.
Glyme may refer to: Any of the glycol ethers, a class of solvents, usually dimethoxyethane if not otherwise specified; River Glyme, a river in Oxfordshire, England
This bacterium was found to survive only if there are lanthanides present in the environment. [101] Compared to most other nondietary elements, non-radioactive lanthanides are classified as having low toxicity. [89] The same nutritional requirement has also been observed in Methylorubrum extorquens and Methylobacterium radiotolerans.
Solvent vapors can also be found in supposedly empty drums and cans, posing a flash fire hazard; hence empty containers of volatile solvents should be stored open and upside down. Both diethyl ether and carbon disulfide have exceptionally low autoignition temperatures which increase greatly the fire risk associated with these solvents.
Substitution reactions in organic chemistry are classified either as electrophilic or nucleophilic depending upon the reagent involved, whether a reactive intermediate involved in the reaction is a carbocation, a carbanion or a free radical, and whether the substrate is aliphatic or aromatic. Detailed understanding of a reaction type helps to ...
Congener (alcohol), substances other than alcohol (desirable or undesirable) also produced during fermentation. Congeners of oleic acids can modify cell membrane behavior, protecting against tumors or having effects on blood pressure. [2]
The simplest alkene, ethylene (C 2 H 4) (or "ethene" in the IUPAC nomenclature) is the organic compound produced on the largest scale industrially. [ 5 ] Aromatic compounds are often drawn as cyclic alkenes, however their structure and properties are sufficiently distinct that they are not classified as alkenes or olefins. [ 3 ]
Within the field of geology, Bowen's reaction series is the work of the Canadian petrologist Norman L. Bowen, [1] who summarized, based on experiments and observations of natural rocks, the sequence of crystallization of common silicate minerals from typical basaltic magma undergoing fractional crystallization (i.e. crystallization wherein early-formed crystals are removed from the magma by ...
