Abstract:This paper demonstrates the usefulness of principal component analysis (PCA) in the study of the dissociation process of oleyl alcohol (cis-9-octadecen-1-ol) as the pure liquid. Fourier transform near infrared (FT-NIR) spectra of the neat alcohol were measured over a temperature range of 6.5-90°C in the 11,500-6000 cm -1 region. The degree of dissociation of the alcohol was determined by the intensities of the first and second overtones of the OH stretching mode of the monomer. PCA on the obtained spectra were… Show more
