Synthesis of nitrogen-containing phenolformaldehyde oligomers (phfo), grafted with vegetable  oils is aimed at the acquisition of new range coating materials. Oil has been used as an example of soybean and linseed oils. The interaction  between phfo and vegetable oil is carried out by  means of functional groups as result of the oxidation prosesses on carbon atoms adjacent to the double bond and the functional groups,including oligomer macromolecules. Physical-chemical properties of nitrogen-containing as result of modification by means of benzoguanamine (bga)  monoalkyl (C8-C12)phfo, grafted with soybean oil is reflected. The probable structure  of the nitrogen-containing monoalkyl(C8-C12)phfo, grafted with soybean oil has been studied by means of NMR- and IR-spectroscopy methods. The mechanism of the occurrence of first and second stages of the process are described.

This paper presents the results of a study of the physical and chemical properties of samples of vegetable oils (sunflower, rapeseed, olive). It has been shown that the viscosity of oils varies from 41.4 to 61.7 cSt at a temperature of 40 ° C for olive and sunflower oils, respectively. The acid numbers of the oil samples were also determined, it was found that the lowest indicator is characteristic of sunflower oil. Pour points of oils also range from -3 to -16 ° C for olive and sunflower oils, respectively. Using the method of IR spectroscopy, functional groups in the composition of samples of vegetable oils were studied and it was shown that the composition of oils contains carbonyl and hydroxyl functional groups, indicating the presence of carboxylic acids. Based on studies of the physical and chemical properties of vegetable oils, it was found that sunflower, olive and rapeseed oils can serve as raw materials for the synthesis of biofuels based on them, since they contain free fatty acids. To obtain biodiesel fuel based on vegetable oils, it is planned to use the transesterification method in the presence of various catalysts (alkaline, acidic, and complex).

In this work, we studied the physicochemical properties of thermally activated defecate at 650°C and studied their neutralizing and adsorption properties in the treatment of acidic wastewater. It was found that after heat treatment at 650°C the main functional groups of the defect, i.e. CaCO3 practical has not changed

Oxidative Processes

The synthesis of nitrogen-containing alkyl(C8–C12)phenol formaldehyde oligomers grafted with vegetable oils was investigated with the aim of creating new materials with the properties of protective coatings. Soybean and linseed oils were used as the vegetable oils. The interaction between phenol formaldehyde oligomers and vegetable oils probably occurs through the functional groups formed as a result of oxidative processes at the carbon atoms in the a-position to double bonds. The probable structure was established using infrared and nuclear magnetic resonance spectroscopy, and the physicochemical properties of the synthesised products were studied.
