1. A study has been made of the structural-group composition of crystals recovered from high-boiling fractions of Noriisk crude oil. It has been shown that these crystals are polycyclic aromatic and hydroaromatic hydrocarbons with empirical formulas

A mass spectrometric method of analysis has been developed for determining the composition of products from the alkylation of phenol with α-olefins. This method permits the determination of mixture concentrations of alkylphenols, paraffinic and olef

1. It has been established that as a result of rearrangement during dissociative ionization, the distribution of the molecular ion peaks in the mass spectra of mixtures of alkyl benzenes has a bimodal character, which enables one to distinguish the p
