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 ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
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.
The lighter analogue of propylene oxide, ethylene oxide, is produced by silver-catalyzed reaction of ethylene with oxygen. Attempts to implement this relatively simple technology to the conversion of propylene to propylene oxide fail. Instead only combustion predominates. The problems are attributed to the sensitivity of allylic C-H bonds.
propylene: allylic oxidation: Mo-oxides (heterogeneous) acrylic acid: plastic precursor propylene, ammonia: SOHIO process: Bi-Mo-oxides (heterogeneous) acrylonitrile: plastic precursor methanol: Formox process: Fe-Mo-oxides (heterogeneous) formaldehyde: basic chemicals, alkyd resins butane: Maleic anhydride process: vanadium phosphates ...
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 ...
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 ...
