In the OMEGA process, the ethylene oxide is first converted with carbon dioxide (CO 2) to ethylene carbonate. This ring is then hydrolyzed with a base catalyst in a second step to produce mono-ethylene glycol in 98% selectivity. [10] The carbon dioxide is released in this step again and can be fed back into the process circuit.
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with ...
Synthesis of block copolymers is one of the most important applications of living polymerization as it offers the best control over structure. The nucleophilicity of the resulting carbanion will govern the order of monomer addition, as the monomer forming the less nucleophilic propagating species may inhibit the addition of the more ...
Ethylamine is used as a precursor chemical along with benzonitrile (as opposed to o-chlorobenzonitrile and methylamine in ketamine synthesis) in the clandestine synthesis of cyclidine dissociative anesthetic agents (the analogue of ketamine which is missing the 2-chloro group on the phenyl ring, and its N-ethyl analog) which are closely related ...
In organic synthesis, the complex diethylaniline·borane (DEANB) is used as a reducing agent. [4] Diethylaniline and dimethylaniline are both used as acid-absorbing bases. The advantage to the diethyl derivative is that [C 6 H 5 NEt 2 H]Cl is non-hygroscopic, in contrast to [C 6 H 5 NMe 2 H]Cl. [5]
Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine. It is an industrially significant commodity chemical, as well as a versatile starting material for fine chemical synthesis. Its main use is in the manufacture of precursors to polyurethane, dyes, and other industrial chemicals.
N-Methylaniline (NMA) is an aniline derivative.It is an organic compound with the chemical formula C 6 H 5 NH(CH 3).The substance is a colorless viscous liquid, Samples turn brown when exposed to air.
Following rearrangement and loss of water, a second equivalent of water attacks the alpha position. Red amorphous selenium is liberated in the final step to give the 1,2-dicarbonyl product. [8] [9]: 4331 Allylic oxidation using selenium-dioxide proceeds via an ene reaction at the electrophilic selenium center.
