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 .
The formation of the oxo-dimer is a process called oxolation: [4] 2 [L n MOH] ⇌ L n M−O−ML n + H 2 O, where L = ligand. Ultimately olation and oxolation lead to metal oxides: 2 [M(H 2 O) 6] 3+ → M 2 O 3 + 9 H 2 O + 6 H + Olation and oxolation are responsible for the formation of many natural and synthetic materials.
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 organic chemistry, the oxy-Cope rearrangement is a chemical reaction.It involves reorganization of the skeleton of certain unsaturated alcohols. It is a variation of the Cope rearrangement in which 1,5-dien-3-ols are converted to unsaturated carbonyl compounds by a mechanism typical for such a [3,3]-sigmatropic rearrangement.
