FIELD: chemistry.
SUBSTANCE: method of producing alkyd resin involves feeding and mixing in a reactor an oil-containing component, glycerine and LiOH, and heating the mixture to 230-260°C, followed by vinylation, polyesterification and bringing to the required characteristics by adding a solvent, wherein vinylation is preceded by alcoholysis, distillation of water without an azeotrope and an alcohol test; after the alcohol test the mixture is cooled to 150-160°C and then undergoes vinylation in the presence of vinyl toluene, xylene, phthalic anhydride and di-tertiary butyl peroxide.
EFFECT: high efficiency of the process and low power consumption owing to a shorter time for synthesis of the alkyd mixture; the obtained resin has improved colour characteristics and shorter drying time to 3rd degree.
