Title:
SYNTHESIS METHOD FOR WIDE-CHROMATOGRAPHIC-BAND IRON OXIDE YELLOW PIGMENT
Document Type and Number:
WIPO Patent Application WO/2023/201973
Kind Code:
A1
Abstract:
A preparation method for a wide-chromatographic-band iron oxide yellow pigment. The preparation method comprises: 1, weighing 0.03-0.08 mol of CTAB (hexadecyl trimethyl ammonium bromide), dispersing in 30-50 mL of deionized water, stirring at room temperature for 30-60 min until a solution becomes transparent, and denoting the solution as a solution A; 2, separately weighing 0.02-0.2 mol of FeCl3 (ferric chloride), dissolving the FeCl3 in the solution A, and stirring for 30-60 min until a homogeneous solution is formed; 3, pouring the solution into a 50 mL Teflon stainless steel high-pressure reaction kettle and carrying out a hydrothermal reaction at 80-120 °C for 6-24 h; 4, after the reaction is completed, cooling the reaction kettle to room temperature; and 5, separately washing with ethanol and distilled water three times and drying at 50-60°. Finally, the wide-chromatographic-band iron oxide yellow with ΔL reaching 5.17 and ΔB reaching 7.18 is obtained.
