MEASUREMENT METHOD FOR PLANT-DERIVED ETHANOL CONTENT IN AUTOMOTIVE FUEL

摘要

PROBLEM TO BE SOLVED: To provide an accurate and easy measurement method of bioethanol in a hydrocarbon-based automobile fuel containing plant-derived ethanol.;SOLUTION: The measurement method for plant-derived ethanol content in hydrocarbon-based automotive fuel comprises performing extraction operation for acquiring a water phase of two separated phases after adding and mixing water to a sample of the hydrocarbon-based automotive fuel containing plant-derived ethanol followed by standing still, and analyzing ¹⁴C quantity in the extract.;COPYRIGHT: (C)2009,JPO&INPIT
