2,4-Dimethylpentane is an alkane with the chemical formula [(H 3 C) 2 CH] 2 CH 2. This colorless hydrocarbon is produced in large quantities in oil refineries. It results from the alkylation of isobutane by propylene. [1] Often referred to as "alkylate", it is blended with other gasoline components to give a high octane fuel.
N,O-Dimethyl-4β-(2-naphthyl)piperidine-3β-carboxylate (DMNPC) is a piperidine based stimulant drug which is synthesised from arecoline. It is similar to nocaine in chemical structure, and has two and a half times more activity than cocaine as a dopamine reuptake inhibitor .
3-Methylheptane is a branched alkane isomeric to octane. Its structural formula is CH 3 CH 2 CH(CH 3)CH 2 CH 2 CH 2 CH 3. It has one stereocenter. Its refractive index is 1.398 (20 °C, D). [citation needed]
Thus, the two substrates of this enzyme are (3S,4R)-3,4-dihydroxycyclohexa-1,5-diene-1,4-dicarboxylate and NAD +, whereas its 3 products are 3,4-dihydroxybenzoate, CO 2, and NADH. This enzyme is a part of the terephthalate degradation pathway in bacteria.
The speed of sound at 3 MHz is 1149.5 m/s at 20 °C and 889.5 m/s at 80 °C. [ 7 ] [ 8 ] [ 9 ] The racemic mixture has a glass transition temperature of about 123 K (−150 °C), but reportedly it does not crystallize—a fact that has been claimed to be a characteristic of high-purity optically active alkanes.
The Ph 3 C-H bond is relatively weak, with a bond dissociation energy (BDE) of 81 kcal/mol, or about 24 kcal/mol less than methane. [4] Correspondingly, triphenylmethane is mildly acidic, with a pK a of 33.297.
The 3 substrates of this enzyme are dodecanoyl-CoA, H 2 O, and 2-oxoglutarate, whereas its two products are (3S,4S)-3-hydroxytetradecane-1,3,4-tricarboxylate and CoA. This enzyme belongs to the family of transferases, specifically those acyltransferases that convert acyl groups into alkyl groups on transfer. The systematic name of this enzyme ...
2,6-Dimethylnaphthalene is mainly used for the preparation of 2,6-naphthalenedicarboxylic acid by oxidation of 2,6-dimethylnaphthalene in the liquid phase. 2,6-Naphthalenedicarboxylic acid is a monomer for the production of high-performance polymers, in particular poly (ethylene-2,6-naphthalene dicarboxylate) or shorter polyethylene naphthalate (PEN).
