Is Propylene Tetramer (CAS 68442-63-7) a single compound or a mixture?

It is a UVCB substance composed of branched C12 olefins formed during propylene oligomerization. The CAS number refers to the industrial mixture rather than a single defined molecular structure.

Is Propylene Tetramer suitable as an alkylation feedstock in industrial processes?

It is commonly used as an alkylation feedstock where C12 olefin reactivity is required, particularly in processes that convert branched olefins into functional intermediates under controlled industrial conditions.

Propylene Tetramer CAS 68442-63-7

Propylene Tetramer is a C12 branched olefin mixture produced through propylene oligomerization and is commonly classified as a propylene-derived olefin, C12 olefin mixture, or propylene oligomer stream. Identified by CAS 68442-63-7, it functions primarily as an alkylation feedstock, where its branched olefin structure participates in downstream alkylation or functionalization reactions to generate higher-value intermediates used in lubricant additives, fuel-related formulations, and specialty hydrocarbon processing. The material’s role is defined by its reactivity as an unsaturated hydrocarbon mixture rather than as a single, purified compound.
In terms of industrial availability, this product is offered with competitive factory pricing, customized specifications, and full documentation including MSDS, TDS, COA, supporting bulk supply for continuous industrial processing requirements.
