An analysis of Zhenghe Group’s acrylic acid quality was released on Dec 16. The acrylic acid had water content of 0.079, purity of 99.7 percent, chromaticity of 10, and polymerization inhibitor levels reaching 204 parts per million. The strong numbers confirm the superiority of the company’s acrylic acid.

Since unit renovation in September, the water content of acrylic acid has stabilized at around 0.08 percent, successfully solving the excess water problem in acrylic acid production. It has not only raised the acceptance rate by nearly 20 percentage points, but also provided valuable references for the improvement of domestic acrylic acid production technology.
