Industrial Grade 1-Hexene
1-Hexene is an acyclic alpha-olefin hydrocarbon (C6H12) with a double bond, derived from petroleum through catalytic cracking and oligomerization processes. It falls under HTS 2901.29.10 as an unsaturated acyclic hydrocarbon other than ethylene, propylene, butene, and butadiene, specifically sourced from petroleum. Commonly used as a comonomer in polyethylene production.
Petroleum-Derived 1-Octene
1-Octene (C8H16) is a linear alpha-olefin produced from petroleum via ethylene oligomerization or Fischer-Tropsch synthesis. Classified under HTS 2901.29.10 as an other unsaturated acyclic hydrocarbon derived from petroleum, distinguished from the first four alkenes. Essential for producing linear low-density polyethylene (LLDPE).
Isoprene (2-Methyl-1,3-Butadiene) Petroleum Grade
Petroleum-derived isoprene (C5H8) is a conjugated diene unsaturated hydrocarbon extracted from C5 fractions of petroleum cracking. HTS 2901.29.10 covers this as an other unsaturated acyclic hydrocarbon from petroleum, not the first four alkenes. Primary use in synthetic rubber (IR, SBR) production.
Petrochem 1-Nonene
1-Nonene (C9H18) is a higher alpha-olefin derived from petroleum propylene telomerization or ethylene metathesis. Falls under HTS 2901.29.10 as petroleum-sourced unsaturated acyclic hydrocarbon beyond basic alkenes. Used in synthetic lubricants, plasticizers, and detergents.
Dicyclopentadiene Petrochemical Grade
Dicyclopentadiene (DCPD, C10H12) is a bicyclic diene dimerized from petroleum-derived cyclopentadiene. Although containing rings, classified under acyclic hydrocarbons (2901) per HTS structure as petroleum-derived unsaturated hydrocarbon. Used in unsaturated polyester resins and EPDM rubber.
Mixed C4 Acetylenes Petroleum Fraction
Mixed C4 acetylenes (1-butyne, 2-butyne, vinylacetylene) recovered from petroleum acetylene processes. HTS 2901.29.10 covers these unsaturated acyclic hydrocarbons with triple bonds derived from natural gas liquids. Used in vinylacetylene-based synthetic rubber intermediates.
