Abstract
Medium active furnace carbon black grade P514 was modified with phenolic acids and experimental samples were obtained under optimal conditions. Their physicochemical properties were studied before and after the adsorption of modifiers (salicylic, sulfosalicylic acid): transportable, ash content, pH, light transmission of toluene extract, absorption of dibutylphthalate, etc. The textural characteristics of the studied samples and the quantitative composition of oxygen-containing groups (carboxyl and phenolic, basic) on their surface.
