Glacial acetic acid is a weak colorless reducing agent when it remains free of water (undiluted). This makes it suitable for use in the plastics and food industries. Although a weak acid, it is mildly corrosive to metals such as iron, magnesium and zinc. When reacted with such metals it forms hydrogen gas and salts. Aluminum tanks are used to transport acetic acid because aluminum forms a passivating acid-resistant film of aluminum oxide. Metal acetates can be prepared from acetic acid and an appropriate base.
Acetic Acid for Textile Dyeing and Printing
Acid dyes are substantive to protein and some polyamide fibers, including silk, wool, and nylon 6.6. Acid dyes are characterized by clear and vivid colors and are used for printing fabrics such as those used for swimwear, high-end fashion dresses, and accessories.
In the printing process, acid dye molecules need to establish ionic bonds with the fibers. Therefore, the print paste typically uses weak acid solutions, such as ammonium sulfate, ammonium tartrate or acetic acid, as a fixing agent to create the negatively charged dye site. The acid is mixed in the print paste together with a thickening agent made from guar gum, locust-bean, crystal gum, etc. The fixation processes are similar to those used for reactive dyes. After steaming with saturated steam, the printed fabrics are washed to remove excess dyes and thickening paste.
