Abstract
MASS-spectrometric methods of identification and quantitative analysis of organic compounds are based on correlations between the molecular structures and the distribution of intensities in their mass-spectra. The investigation of the mass-spectra of hydrocarbons made it possible to establish several relations to determine the types of hydrocarbons in such complex mixtures as petroleum fractions [1-4]. Problems of mass-spectrometric analysis of alcohols are discussed in the literature to a considerably lesser extent. This report discusses results of an investigation of the mass-spectra of heptan-l-ol, heptan-2-ol, heptan-3-ol and hcptan-4-ol and a mixture of C 7 alcohols separated from products of oxidation of n-heptane in the presence of boric acid [5]. The physical constants of individual alcohols-density, refractive index, boiling point and methods of preparation are described in reference [5]. The study was carried out in MKh-1303 and MS-1 mass-spectrometers modified according to the description given ealier [2]. Operating conditions.
