About Us

    Yuli Chemical is a company in China’s fine chemical industry specializing in air oxidation, acetylation, and chlorosulfonation reactions.
The company established its plant in 2005 at the Duigougang Chemical Industrial Park in Guannan County, Lianyungang, Jiangsu Province. In 2012, it formed a joint venture with a Japanese listed company, Air Water Yuli Chemical. Later, due to policy adjustments in the industrial park, a new cooperative production base was established in Yumen, Gansu.
Yuli Chemical focuses on custom manufacturing and specialty chemicals such as 1-naphthoic acid and 2-naphthoic acid. Leveraging its unique oxidation reaction capabilities, the company’s main products include 4,4'-diphenyl ether dicarboxylic acid, 4-ethylbenzoic acid, veratric acid, 2,4-dimethylbenzoic acid, and 2,5-dimethylbenzoic acid. 3-Methoxy-2-methylbenzoic acid is also commercially produced using a proprietary developed route. Additionally, co-produced products such as phthalaldehyde, terephthalaldehyde, and isophthalaldehyde derivatives are particularly distinctive.
The plant is equipped with multiple imported HPLC, GC, UV, ion chromatography (ICP), and ion removers, providing strong support for product analysis and quality control.
We look forward to your cooperation and support.
