Gas Purification Absorbs carbon dioxide and hydrogen sulfide from gases. Solvents Gas chromatography stationary phase (maximum operating temperature 50°C, solvent: ether), used for separating lower alcohols, pyridine, and its derivatives. Pharmaceuticals Synthetic bactericide, antidiarrheal agent. Dyeing and Printing Synthetic high-grade dye (condensation-polymerized turquoise blue 13G). Textiles Used as a fluorescent brightener, antistatic agent, mothproofing agent, and detergent. Rubber Ink Used as a neutralizer, plasticizer, vulcanizer, accelerator, and foaming agent. Others Also used in surfactants, petroleum additives, preservatives, ink manufacturing, and organic synthesis raw materials. It can also be used as a raw material for metal cleaners and rust inhibitors; a processing aid for the food industry; in the manufacture of non-ionic detergents, emulsifiers, and automotive antifreeze; and as a raw material for the production of ethyleneamine products.
