3 Acrylic Acid Industry Standards Approved

At the inaugural meeting of the Sixth Committee of the Petrochemical Branch of the National Chemical Standardization Technical Committee held in Hangzhou recently, the Liaoyang Petrochemical Company drafted and revised the spectrophotometric method for the determination of the content of "fine technical adipic acid" and "fine adipic acid**". The three industry standards for “Method for determining weight loss of moisture content of adipic acid” have been approved. The preparation and amendment of the series of refined adipic acid standards will provide a strong guarantee for guiding the industry in producing and regulating the market.

Participating experts believe that the "industrial adipic acid industry standards" in the product quality indicators have reached the international advanced level, to create favorable conditions for the import and export of adipic acid; "Specific adipic acid ** content of the determination of spectrophotometry “There are many innovations in the industry standards that have improved the reproducibility of the original method and provided accurate and reliable technical means for the detection and control of product quality; the “Determination of the moisture content of hexanedioic acid” has changed the previous The method of measurement, on the premise of ensuring the accuracy of measurement, no longer uses toxic and hazardous reagents.

In recent years, after industrial restructuring, Liaoyang Petrochemical's refined adipic acid production capacity has accounted for 30% of the national adipic acid market, making it the largest supplier of refined adipic acid in China.
