REFORMULATED GASOLINE TEST APPARATUS USING DYES TO DISCRIMINATE THE REFORMULATED GASOLINE WITH THE NAKED EYE

摘要

PURPOSE: A reformulated gasoline test apparatus using dyes is provided, thereby easily and rapidly discriminating the reformulated gasoline with the naked eye. CONSTITUTION: The reformulated gasoline test apparatus using dyes comprises a dye sensing portion which contains one or more dyes of which colors are changed by reacting them with a specific volatile component, and is positioned at regular intervals, wherein the dye is a metal complex of which color is changed by reacting with methyltributylether(MTBE); the metal complex is selected from Pt, Pd, Cu, Ni, Co, Na, Cs, Re, Se, Zn, Te and Fe complexes; the dye is pH dye of which color is changed by reacting with toluene; and the pH dye is selected from N-(4-pyridylmethylidene)-4-amino-2,6-dichlorophenol, Reichardt's dye, Nile red, methyl red, prodan, 1-(4-nitrophenyl)-6-phenylhexatriene, 4-(N,N-dioctylamine)- 4'-trifluoroacetylazobenzene, 4-(N,N-dioctylamine)- 4-(4-trifluoroacetylazo)-naphthalene, and 2,5-bis-(3-(5-sulfo-2,3-dihydro-1H-indol-1-yl)-2-propenylidene)-cyclopentanone.
