Study of the structural-dynamic characteristics in mixtures of petroleum and synthetic oils

Spin-probe EPR spectroscopy has shown that the introduction of synthetic components of dioctylsebacate (DOS), dioctyladipate (DOA) and dioctylphthalate (DOP) increases the phase heterogeneity, as indicated by the change in the structural-dynamic properties of the medium. It has been established that DOA, DOS and DOP react with the microstructures formed by aromatic hydrocarbons, changing their structure. With a concentration of only 5-10%, dioctyladipate forms fairly stable «domains» of pure DOA. Dioctylsebacate and dioctylphthalate change the structure of native microfonnations, increasing their density in the 55% concentration region, and they form their own microphase at higher concentrations (> 60%)
