Abstract

IR spectra of mixtures of mineral oil and isopropyl myristate modeling motor oils with different concentrations of esters were studied. A relationship between the absorption band intensities at 1737, 1180, and 1110 cm−1 and the ester concentration in the oil was revealed. A procedure was proposed for the determination of esters in motor oils by IR spectrometry (cmin = 1%; RSD ≤ 8.6%). The procedure was tested on several commercially available samples of lubricants (RSD ≤ 12%).
