  • Detail

On December 30, 2010, good news came from Jiangxi Yichun Yuanda Chemical Co., Ltd. that the low phosphorus dimer acid project applied by the company was supported by 700000 yuan loan from the technology innovation fund management center for scientific and technological small and medium-sized enterprises of the Ministry of science and technology

huangronglai, chairman of Yuanda chemical company, told that the company's low phosphorus dimeric acid project took the lead in adopting the patented technology of washing and separation in China through the improvement of the production process of dimeric acid, which removed the phosphate radical introduced due to acidification, reduced the pollution of phosphate radical to dimeric acid, reduced the phosphate radical content of the finished dimeric acid to less than 30ppm, improved the quality of dimeric acid, and greatly improved the performance of its downstream products, The application field of dimeric acid is widened. Their innovative low phosphorus dimer acid process is mature, simple, low-cost and safe to operate. The products they produce have been tested by Jiangxi Provincial analysis and testing center and tried by air products company of the United States, and fully comply with international standards

it is reported that low phosphorus dimeric acid is a necessary testing instrument for the quality testing departments of various research institutes and pipe manufacturers. It is a new product independently developed by Yuanda chemical company according to the market demand. It has obtained the key new product certificate of Jiangxi Province and has applied for the invention patent. Dimeric acid is a kind of chemical product intermediate prepared from vegetable oleic acid by catalytic polymerization, phosphoric acid acidification and molecular distillation separation. Due to the need to add excessive phosphoric acid for acidification in the production process, there is a great friction between the upper and lower end faces of the product and the support of the experimental machine. The phosphate radical in the dimer acid cannot be removed, which greatly affects the quality of the dimer acid
