PB15 Kodlu Pigmentler; Sentezi, Karakterizasyonu ve Endüstriyel Uygulamaları

Ftalosiyaninler (Pc’ler) yapısal olarak makro halkalı porfirin türevlibileşiklere benzemektedirler. Ftalosiyaninlerin genellikle farklıçözünürlük, renk şiddeti ve kararlılık açısından birbirinden ayrı en aziki kristal modifikasyonu bulunmaktadır. Renk şiddeti (pigmentözelliği) en kuvvetli olan türevleri bakır, kobalt ve nikelftalosiyaninlerdir. Pigment olarak ticari öneme sahip tek ftalosiyaninbakır ftalosiyaninlerdir. Bakır ftalosiyaninler (CuPc, PB15), sayılanbu üstün özellikleri nedeniyle, baskı mürekkepleri, tekstil, kâğıt,kauçuk ve plastiklerin renklendirilmesinde ve hatta inşaat veendüstriyel boya üretiminde kullanılmaktadır. Bu çalışmada,ülkemizde üretilmeyen ancak ithal edilip yaygın bir şekilde kullanılanftalosiyanin türevli, PB15:1 kodlu (bu kapsamda sentezlenenpigmente HNS 15:1 kodu verilmiştir) pigmentin sentezi,karakterizasyonu ve endüstriyel uygulama örnekleri yapılmıştır.Pigmentin sentezinde uygun başlangıç maddeleri yağ ısıtmalı birreaktörde karıştırılmış ve ham ürün elde edilmiştir. Reaksiyondanelde edilen ham ürün yıkanmış, filtre edilmiş ve kurutulmuştur. Eldeedien pigment UV-vis., FTIR, MS gibi spektroskopik teknikler veelementel analiz ile karakterize edilmiştir. Pigmentin endüstriyeluygunluk denemeleri masterbatch, suni deri ve pigment pastasektörlerinde yapılmıştır.

PB15 Coded Pigments; Synthesis, Characterization and Industrial Applications

Phthalocyanines (Pcs) are structurally similar to macrocyclicporphyrin-derived compounds. Phthalocyanines generally have at least two crystal modifications that are distinct from each other in terms of solubility, color intensity and stability. The strongest derivatives in terms of color intensity (pigment property) are copper, cobalt and nickel phthalocyanines. The only phthalocyanine having commercial value as pigment is copper phthalocyanine. Copper phthalocyanines are also used in printing inks, textiles, paper, rubber and plastics, and even in the production of construction and industrial paint thanks to their outstanding properties. In this study, production, characterization and experimentation on industrial applications of the phthalocyanine-derived, PB15: 1 coded pigment (In this study, HNS 15: 1 code is given to the synthesized pigment) which is not produced but widely used in our country, have been successfully implemented. In the synthesis of the pigment, suitable starting materials were mixed in an oil-heated reactor and the crude product was obtained. The crude product from the reaction was washed, filtered and dried. The obtained pigment was characterized by spectroscopic techniques such as UV-vis., FTIR, MS, and elemental analysis. Industrial compatibility tests of pigment are made in the masterbatch, artificial leather and pigment pastry sectors.
