Technical Specialist The main downfall of butane is that it boils at 32°F. 1-Octene is one of the important linear alpha olefins in industry. Octane stability in racing fuels is much different because fuel quality is valued more than production cost, unlike the pump gas industry where cost drives the majority of refining decisions. The butane vapor pressure issue is addressed with the use of chemical components that boil around 80°F. 1-Octene is an organic compound with a formula CH2CHC6H13. Cold weather fuel has higher concentrations of butane. Point (o C) Boiling Point (o C) State at 25 o C: methane: CH 4-183-164: gas: ethane: C 2 H 6 … In this article we will focus on octane stability of 87 and 93 octane pump fuels versus racing fuels and what you can do to prevent octane loss in your fuel. Octane ratings are important because different engines expose fuel to different amounts of pressure and heat. It is a colourless liquid. NIST / TRC Web Thermo Tables, professional edition (thermophysical and thermochemical data) As a result the octane can decrease within months for 87 octane fuels, especially when stored under less than ideal conditions. Keep in mind that 93 octane fuels are still susceptible to octane loss and vapor pressure decreases due to butane evaporation. The additive is stable in gasoline as long as no UV light hits the fuel. Sunoco 260 GT Plus is our only race fuel that contains MMT. In order to achieve high octane and consistent composition, pure chemical components are mixed with highly refined gasoline. s; CAS no: 111659; Data type: Normal alkane RI value specified by scale definition; Authors: von Kovats, E., 206. Teil 1: Retentionsindices aliphatischer Halogenide, Alkohole, Aldehyde und Ketone, Helv. The butane vapor pressure issue is addressed with the use of chemical components that boil around 80°F. Boiling Point: 126.4±3.0 °C at 760 mmHg Vapour Pressure: 14.2±0.1 mmHg at 25°C Enthalpy of Vaporization: 34.4±0.0 kJ/mol Flash Point: 15.6±0.0 °C Index of Refraction: Acta, 41(7), 1958, 1915-1932. https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:17590, ACD/Labs Percepta Platform - PhysChem Module, US Environmental Protection Agency’s EPISuite, Compounds with the same molecular formula, Search Google for structures with same skeleton, 257-259 F / 760 mmHg (125-126.1111 °C / 760 mmHg), 258 F / 760 mmHg (125.5556 °C / 760 mmHg), Soluble in ether, Slightly soluble in alcohol. If stored in a vapor tight container the vapor pressure can be maintained for long periods of time. Pump fuels with high (12 pounds/square inch, psi) vapor pressures are used in cold weather to prevent engine starting issues due to low temperatures. https://www.epa.gov/gasoline-standards/gasoline-reid-vapor-pressure, L.

Kapron (1975) Methylcyclopentadienyl Manganese Tricarbonyl as an Antiknock: Composition and Fate of Manganese Exhaust Products, Journal of the Air Pollution Control Association, 25:8, 858-859, DOI: 10.1080/00022470.1975.10470152. Octane is a hydrocarbon and an alkane with the chemical formula C8H18, and the condensed structural formula CH3(CH2)6CH3. This makes cold weather fuel more susceptible to vapor pressure loss and octane decreases. Octane stability is greatly affected by the storage conditions. That is why we provide proper storage information on our website. Pump fuels are limited to 7.8-9psi maximum in warm weather depending on county and state (www.epa.gov).

A key aspect of gasoline stability is vapor pressure. These stable hydrocarbons can last 2-3 times longer than 87 octane fuel. Sunoco Race Fuels, http://www.sunocoracefuels.com/tech-article/race-fuel-storage. Colorless liquid with a gasoline-like odor. Some high octane unleaded fuels, 260 GT Plus, and octane boosters contain the additive MMT. We have test results confirming octane stability in our unleaded, leaded, ethanol-free and ethanol fuels.
