Abstract
Ushbu maqolada tarkibida qo‘shmetall saqlagan vismut-kobalt ftalosianin (Bi-Co–Pc) pigmentining sintez jarayoniga boshlang‘ich reaktivlar nisbati va haroratning ta’siri o‘rganildi. Sintez jarayoni 150-200 °C oralig‘idagi haroratlarda FA:Kar:Bi(NO3)3:CoCl2 larni turli nisbatlarida amalga oshirildi. Olingan natijalar shuni ko‘rsatdiki, mahsulot unumiga harorat va boshlang’ich reaktivlar nisbatining xususan, FA:Ka Bi(NO3)3:CoCl2 200 °C haroratda maksimal unum -41,5% ni tashkil etdi. Tahlillar asosida reaksiyaning optimal sharoitlari aniqlanib, bu ko‘rsatkichlar qo`shmetall ftalosianinlar sintezining samaradorligini oshirish uchun muhim amaliy ahamiyatga ega ekanligi isbotlandi. Sintez natijasida olingan vismut-koblt ftalosianin pigmentining infraqizil (IQ) spektral tahlilida ftalosianin halqasidagi (–C–N–C–) bog‘lar, shuningdek, metall–azot bog‘lari (Bi–N, Co–N) mavjudligi aniqlangan.References
