Abstract: The effects of synthesis conditions on characteristics of the calcium-azo complex pigment, C.I. Pigment
Red 57:1, were studied. It was mainly considered that the industrially required synthesis conditions for lowering
electrical conductivity of the pigment solution keeping pigment quality such as particle size and color
characteristics. Three parameters were chosen as control factors during the synthesis. The first was the amount of
hydrochloric acid added to transform sodium nitrite into nitrous acid. The second was the amount of calcium
chloride added to insolubilize the synthesized azo dye. The final factor was pH control during the coupling
reaction. The electrical conductivity and pigment aggregate particle size were dependent on the amount of
hydrochloric acid and calcium chloride. Higher HCl concentration gave brighter yellowish-red color because of
smaller particle aggregate size and narrower size distribution. Amount of charged ions in the synthesis process
might affect the “lake” formation resulting different particle aggregate size and color shade. |
