Propylene tetramer CAS 6842-15-5

Aure Chemical Supplies Premium Propylene Tetramer CAS 6842-15-5 for Global Industries

Propylene tetramer is a branched C12 olefin cut obtained by oligomerization of propylene. It is typically supplied as a colorless to pale yellow liquid and is used as an alkylation feedstock for dodecylphenol, specialty surfactants and related intermediates. Aure Chemical supplies Propylene tetramer (CAS 6842-15-5) for industrial customers who need a documented C12 olefin stream and export-ready paperwork.

Basic Information of Propylene Tetramer

Commercial material is an isomer mixture rather than a single structure, so physical constants are given as commonly cited ranges. Confirm the current specification and SDS for the exact distillation cut being purchased.

Key Applications of Propylene Tetramer

• Alkylation feedstock for branched C12 aromatics: Propylene tetramer is used to alkylate benzene or phenol, giving branched dodecylbenzene and dodecylphenol intermediates that feed surfactant and lubricant-additive chemistry.

• Lubricant-additive intermediates: Dodecylphenol derived from the tetramer is further converted into calcium alkyl phenates and related detergent/inhibitor packages for engine oils.

• Specialty surfactant building block: It is used in the manufacture of selected branched-chain surfactants, including dodecyl diphenyl oxide sulfonates for latex, rubber and textile systems.

• Fine-chemical and polymer auxiliaries: Downstream products include tert-dodecyl mercaptan, tert-dodecylamine, isotridecanol and tetrapropylene succinic anhydride used as chain-transfer agents, anti-rust intermediates and epoxy-related additives.

• Coatings and plasticizer chemistry: The C12 olefin cut also serves as a starting olefin for selected plasticizer, emulsifier and coating intermediates where a branched dodecyl chain is required.

• Application-oriented sourcing support: Technical discussion is available on cut selection, packaging and shipment planning for dodecylphenol, TDM and related downstream routes.

Hazards Classification

GHS Classification: Flammable liquid (Category 3, GHS02); Aspiration hazard (Category 1, GHS08); Hazardous to the aquatic environment, acute and chronic (Category 1, GHS09). Eye irritation (Category 2, GHS07) is also listed on some commercial SDS.

Hazard Statements: H226 Flammable liquid and vapor; H304 May be fatal if swallowed and enters airways; H410 Very toxic to aquatic life with long lasting effects. Repeated skin contact may cause dryness or cracking (EUH066 on some records).
