QUICK TEST METHOD AND KIT FOR DETERMINATION OF ETHANOL CONTENT IN ETHANOL BLENDED MOTOR SPIRIT (EBMS)

摘要

Embodiments of the present disclosure relate to a method for quantitative estimation of an amount of ethanol in a petroleum sample, said method including the steps of (a) contacting an appropriate amount of the petroleum sample with an appropriate amount of a dye suspension, wherein the dye suspension comprises about 0.5% crystal violet dye dispersed in paraffin oil; (b) obtaining a color, based on a reaction between the petroleum sample and the dye suspension after a pre-defined time interval, wherein the obtained color is proportional to the amount of ethanol in the petroleum sample over an ethanol concentration ranging from 6% to 10%; and (c) estimating the amount of the ethanol based on the obtained color. Embodiments of the present disclosure further provide a kit for qualitative and quantitative estimation of ethanol in a petroleum sample.
