NEW PIGMENTS BASED ON TEREPHTAL ACID:SYNTHESIS AND PROPERTIES. DEVELOPMENT OF THE TECHNOLOGY OF OBTAINING ORGANIC PIGMENTS BASED ON TEREPHTAL ACIDMONOGRAPH

      Аннотация: Today, targeted scientific research is being carried out in the world in areas that include organic pigments based on highly effective terephthalic acid. As we know, synthetic organic pigments began to be produced in the second half of the 19th century. Thousands of pigments of this type have been used in various industries such as paints, printing inks, and dyeing plastics and textiles. In this regard, special attention is paid to the development of high-quality and competitive pigments based on phthalocyanines containing nitrogen, phosphorus, and other elements, to the research of the properties of pigments, and to the development of their production technology.Phthalocyanine pigments containing new organic compounds have been created in our republic based on new innovative technologies, certain scientific and practical results have been achieved with the help of these phthalocyanine pigments to obtain pigments with high color intensity, thermal stability, and resistance to external influences, especially effective research aimed at creating phthalocyanine pigments based on a new approach is being conducted.
