Abstract

NEW MATERIAL:1-Amino-4-bromoanthraquinone-2-sulfonic acid sodium salt having a crystal structure characterized by the X-ray diffraction peaks (2θ) of 8.1°, 12.2° and 16.2°, or 11.2°, 16.5° and 25.0° wherein θ is the diffraction angle measured by the powder X-ray diffractometry with Cu-Kα (1.54Å).
USE: Intermediate of anthraquinone acidic dye or reactive dye. Stable at high temperature, and highly reactive.
PROCESS: 1-Amino-4-bromoanthraquinone-2-sulfonic acid sodium salt prepared by conventional process is heated at 120W450°C to afford the objective compound.
