Standard Test Method for Determination of MTBE, ETBE, TAME, DIPE, tertiary-Amyl Alcohol and C1 to C4 Alcohols in Gasoline by Gas Chromatography.
Get more information about the standard at ASTM D4815-22.
ASTM D4815 is a standard analytical procedure used to identify and quantify oxygenates and hydrocarbons in gasoline. The method ensures fuel compliance with regulatory standards, especially for oxygenate content, which is crucial for meeting environmental requirements and improving combustion efficiency.
Details
The ASTM D4815 test method is based on gas chromatography (GC), which separates and quantifies individual components in gasoline samples. It focuses on oxygenates such as MTBE (Methyl Tertiary-Butyl Ether), ETBE (Ethyl Tertiary-Butyl Ether), TAME (Tert-Amyl Methyl Ether), DIPE (Diisopropyl Ether), tert-butanol, and other alcohols (methanol, ethanol, isopropanol). Additionally, it provides data on C5-C12 hydrocarbons present in gasoline.
Industries & Applications
ASTM D4815 is widely used across industries such as:
- Petroleum and refining: Refineries use this method to monitor and control oxygenate blending in gasoline formulations
- Fuel Testing laboratories: Labs rely on the method for quality control and regulatory compliance testing
- Automotive industry: Ensures compatibility of fuel with vehicle engines and emissions systems
- Environmental agencies: Used to verify fuel composition for compliance with air quality regulations
- Renewable fuel producers: Ethanol and biofuel producers use it to measure blending proportions with gasoline
