Quantitative method using differential infrared spectrometry for the determination of compound types absorbing in the carbonyl region in asphalts.
Anal Chem 1975 Jan; 47(1):112-117
A method for the qualitative and quantitative determination of ketones, dicarboxylic anhydrides, carboxylic acids, and 2-quinolone types in asphalt is presented. The technique is based on differential infrared spectrometry combined with base hydrolysis and silylation reactions. Determinations are made using simple laboratory equipment without the necessity of reagent or reaction product separation.
