Grignard reagents add to propylene oxide to give secondary alcohols. Some other reactions of propylene oxide include: [14] Reaction with aluminium oxide at 250–260 °C leads to propionaldehyde and a little acetone. Reaction with silver(I) oxide leads to acetic acid. Reaction with sodium–mercury amalgam and water leads to isopropanol.
Alkoxylation is a chemical reaction that involves the addition of an epoxide to another compound. The usual manifestation of this reaction is ethoxylation of alcohols (ROH), in which case ethylene oxide is the alkoxylating agent: ROH + C 2 H 4 O → ROCH 2 CH 2 OH. Another industrially significant epoxide is propylene oxide (PO, OCH 2 CHCH 3 ...
Starting with propylene chlorohydrin, most of the world's supply of propylene oxide arises via this route. [3] An intramolecular epoxide formation reaction is one of the key steps in the Darzens reaction. In the Johnson–Corey–Chaykovsky reaction epoxides are generated from carbonyl groups and sulfonium ylides. In this reaction, a sulfonium ...
As the basic building block is propylene oxide, there are 3 carbons per oxygen on the backbone. This confers some degree of water miscibility though not as good as ethylene oxide based molecules. [10] It is used to synthesize the epoxy reactive diluent and flexibilizer, Poly(propylene glycol) diglycidyl ether.
Propylene is also used to produce isopropyl alcohol (propan-2-ol), acrylonitrile, propylene oxide, and epichlorohydrin. [18] The industrial production of acrylic acid involves the catalytic partial oxidation of propylene. [19] Propylene is an intermediate in the oxidation to acrylic acid.
ethylbenzene is oxidized to ethylbenzene hydroperoxide, an epoxidizing agent in the propylene oxide/styrene process POSM; In the Bashkirov process, the autoxidation is conducted in the presence of boric acid, yielding an intermediate borate ester. The process is more selective with the boric acid, but the conversion to the alcohol requires ...
Cumene hydroperoxide is involved as an organic peroxide in the production of propylene oxide by the oxidation of propene. This technology was commercialized by Sumitomo Chemical. [6] The oxidation by cumene hydroperoxide of propene affords propylene oxide and the byproduct 2-phenylpropan-2-ol. The reaction follows this stoichiometry: CH 3 CHCH ...
A typical well-known method of preparation is the reaction of potassium hydroxide with 3-chloropropyl acetate at 150 °C: [2]. Yield of oxetane made this way is c. 40%, as the synthesis can lead to a variety of by-products including water, potassium chloride, and potassium acetate.
