Process for the determination of benzoate in ethyl alcohol denatu00f4nio commercial derivative spectrophotometry

摘要

Process for the determination of benzoate in ethyl alcohol denatu00f4nio commercial derivative spectrophotometry. The present invention relates to a process for quantifying denatu00f4nio benzoate (bitrex) in commercial samples to 46% (M / M) of denatured ethyl alcohol.Using derivative spectrophotometry, preferably, in the fourth order (al = 10) of the absorption spectrum, in 263,0 nm, aiming at its application in the industry of production of alcohol densaturado, intended mainly to quality control in the production of alcohol denatured with Bi Trex.
