Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
1-Phenylethanol is the organic compound with the formula C 6 H 5 CH(OH)CH 3. It is one of the most commonly available chiral alcohols. It is a colorless liquid with a mild gardenia-hyacinth scent.

Crotonic acid has 4 carbons, is included in croton oil, and is a trans-2-mono-unsaturated fatty acid.C 3 H 5 CO 2 H, IUPAC organization name (E)-but-2-enoic acid, trans-but-2-enoic acid, numerical representation 4:1, n-1, molecular weight 86.09, melting point 72–74 °C, boiling point 180–181 °C, specific gravity 1.027.
Phenethyl alcohol is prepared commercially via two routes. Most common is the Friedel-Crafts reaction between benzene and ethylene oxide in the presence of aluminium trichloride. C 6 H 6 + CH 2 CH 2 O + AlCl 3 → C 6 H 5 CH 2 CH 2 OAlCl 2 + HCl. The reaction affords the aluminium alkoxide that is subsequently hydrolyzed to the desired product.
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
1-Phenylethylamine is the organic compound with the formula C 6 H 5 CH(NH 2)CH 3. This primary amine is a colorless liquid is often used in chiral resolutions . Like benzylamine , it is relatively basic and forms stable ammonium salts and imines .
The pharmacokinetics of phenylethanolamine, after intravenous administration to dogs, were studied by Shannon and co-workers, who found that the drug followed the "two-compartment model", with T 1/2 (α) ≃ 6.8 mins and T 1/2 (β) ≃ 34.2 mins; the "plasma half-life" of phenylethanolamine was therefore about 30 minutes.
