Glacial Acrylic Acid

Glacial Acrylic Acid (CAS No. 79-10-7) or 2-propenoic acid is the starting point for all acrylic chemistry. It can be reacted with alcohols to form esters know as acrylates. Acrylic acid and it's esters are used as the components for polymers used in adhesives, coatings, inks, plastics, elastomers, water treatment, personal care, and various other industries. Glacial Acrylic Acid is highly susceptible to dimerization and must be handled with care. If frozen, extreme precaution should be taken to thaw the monomer to prevent a run away polymerization and potential explosion.

1. Temperature control: Acrylic acid should be stored at temperatures between 14 ~ 30°C. Ideally, storage temperature should be controlled at about 20°C to inhibit dimerization. Above freezing, the lower the temperature, the more polymerization can be avoided.

2. Preventing polymerization: To prevent polymerization of acrylic acid, inhibitors such as 200 ppm hydroquinone monomethyl ether are commonly used. These inhibitors only work at room temperature and in the presence of oxygen, so acrylic acid should not be used in an inert atmosphere.

3. Avoid contamination: Acrylic acid should be kept free of contamination during storage because many substances, such as peroxides, nitrogen-containing compounds and polyvalent metal ions, can initiate polymerization.

4. Periodic inspection: Tanks, piping and portable tanks should be inspected periodically for polymerization. Agglomerates and small particles from polymerization may further initiate polymerization.

5. Prevent corrosion: Acrylic acid is highly corrosive to many metals such as unalloyed steel, copper, brass, etc. When these metals decompose, polyvalent polymerization can occur. Decomposition of these metals can produce polyvalent metal ions that can initiate polymerization reactions. Therefore, these metals should be avoided in the storage and transportation of acrylic.

Kaitai Petrochemical was founded in July 2004. With the strong support of all sectors of society, it established a subsidiary in Gaoqing County in 2011 and officially put into production in October 2013. Since 2018, Kaitai has newly put into operation the 180000 tons high-end white oil project of its subsidiary. Kaitai Petrochemical has developed into a diversified chemical group company.
Shandong kaitai is located in beautiful Qi ancient capital- Zibo, which enjoys superior geographic position and convenient traffic- north to Huanghe River, east to Qingdao port, and south to the Jinan airport, Shandong Kaitai never ceases its effort to serve customers, and sold acrylic acid esters to most parts of China and overseas. Kaitai is a comprehensive enterprise integrating acrylic acid, acrylic ester and white oil production.
