Hydroformylation of an alkene (R 1 to R 3 organyl groups (i. e. alkyl-or aryl group) or hydrogen). In organic chemistry, hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes (R−CH=O) from alkenes (R 2 C=CR 2).
Long chain oxo-alcohols are often prepared using alpha-olefins from the Shell higher olefin process, to give secondary alcohols such as isodecyl alcohol. [2] Key oxo alcohols that are sold in commerce include the following: 2-Methyl-2-butanol (2M2B) n-Butanol; 2-Ethylhexanol; 2-Propylheptanol; Isononyl alcohol; Isodecyl alcohol
Oxo-degradation refers to the breakdown mechanism caused by heat, light or oxygen on plastics that contain additives that accelerate the process of breaking them into smaller fragments called microplastics. [1] These plastics contrast biodegradable or compostable plastics, which decompose at the molecular or polymer level. [2]
a) Doubly bridging and b) terminal oxo ligands. A transition metal oxo complex is a coordination complex containing an oxo ligand. Formally O 2–, an oxo ligand can be bound to one or more metal centers, i.e. it can exist as a terminal or (most commonly) as bridging ligands. Oxo ligands stabilize high oxidation states of a metal.

The Shell higher olefin process (SHOP) is a chemical process for the production of linear alpha olefins via ethylene oligomerization and olefin metathesis invented and exploited by Shell plc. [1] The olefin products are converted to fatty aldehydes and then to fatty alcohols , which are precursors to plasticizers and detergents .
If produced from oleochemical feedstock or the Ziegler process, the hydrocarbon chain of the alcohol will be linear. If derived using the oxo process, a low level of branching will appear usually with a methyl or ethyl group at the C-2 position, containing even and odd amounts of alkyl chains. [3] These alcohols react with chlorosulfuric acid:
In enzymology, an oxalate oxidase (EC 1.2.3.4) is an oxalate degrading enzyme that catalyzes the chemical reaction: . oxalate + O 2 + 2 H + 2 CO 2 + H 2 O 2. The 3 substrates of this enzyme are oxalate, O 2, and H +, whereas its two products are CO 2 and H 2 O 2.
An oxo-Diels–Alder reaction (also called an oxa-Diels–Alder reaction) is an organic reaction and a variation of the Diels–Alder reaction in which a suitable diene reacts with an aldehyde to form a dihydropyran ring. This reaction is of some importance to synthetic organic chemistry.
