FIELD: chemistry.
SUBSTANCE: invention describes a method for quantitative determination of organic compounds in binary mixtures by measuring thermal effects of polymorphic transitions occurring during decomposition of products of saturating tert-butylcalix[6]arene with compounds of a binary mixture selected from: cyclohexane, chloroform, dimethyl sulphoxide, pyridine and from: benzene, tetrachloromethane, acetonitrile, acetone, dichloromethane, toluene. Quantitative analysis of content of organic compounds in binary mixtures is carried out based on a calibration curve of thermal effects of processes of decomposition of products of saturating tert-butylcalix[6]arene with said mixtures versus content of components in the mixture.
EFFECT: method enables to conduct quantitative analysis of binary mixtures of a known composition or mixtures where the component which does not induce phase transition of calixarene is known, wherein the analysed components can have similar physical and chemical properties.
