Phenethyl alcohol, or 2-phenylethanol, is an organic compound with the chemical formula C 6 H 5 CH 2 CH 2 OH. It is a colourless liquid with a pleasant floral odor.
The EWG removes electron density from a π system, making it less reactive in this type of reaction, [2] [3] and therefore called deactivating groups. EDGs and EWGs also determine the positions (relative to themselves) on the aromatic ring where substitution reactions are most likely to take place.
NFPA 704 safety squares on containers of ethyl alcohol and acetone. "NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association.
2-Phenylethyl bromide is an organobromide with the formula C 6 H 5 CH 2 CH 2 Br. It is a colorless liquid, although older samples appear yellow. Analogous to the preparation of most 1-bromoalkanes, it is prepared by free-radical addition of hydrogen bromide to styrene.
Monobromotoluene isomers [1] [2] [3] Common name Structure Systematic name: 1-bromo-2-methylbenzene 1-bromo-3-methylbenzene 1-bromo-4-methylbenzene Molecular formula: C 7 H 7 Br (C 6 H 4 BrCH 3) Molar mass: 171.03 g/mol Appearance colorless liquid colorless liquid white crystalline solid CAS number [95-46-5] [591-17-3]
Like all primary and secondary perfluoroalcohols, trifluoromethanol eliminates hydrogen fluoride in an endothermic reaction [3] and forms carbonyl fluoride. [4] CF 3 OH ⇌ COF 2 + HF (I) At temperatures in the range of -120 °C, trifluoromethanol can be prepared from trifluoromethyl hypochlorite and hydrogen chloride: CF 3 OCl + HCl → CF 3 ...
As a solution in tert-amyl alcohol, it has the brand name Avertin. [8] The tert -amyl alcohol acts as a weak hypnotic , in addition to improving the solubility of the tribromoethanol. Administered intravenously, tribromoethanol (Avertin) causes rapid and deep anesthesia followed by rapid and full postoperative recovery in small mammals. [ 9 ]
In commercial applications, the alkylating agents are generally alkenes, some of the largest scale reactions practiced in industry.Such alkylations are of major industrial importance, e.g. for the production of ethylbenzene, the precursor to polystyrene, from benzene and ethylene and for the production of cumene from benzene and propene in cumene process:
