International N-methylpyrrolidone production ,with production capacity growing at an average annual rate of 8%-10%. Domestic NMP manufacturers have more and more scattered manufacturers, and the production capacity is relatively small. With the continuous improvement of R&D strength and the improvement of process equipment, the domestic NMP market still has a lot of room for development and shows a good growth momentum.
Hefei Teng Chao Chemical Material Co.,Ltd produce variety of kinds of N-methyl pyrrolidone,includes techinical grade,industrial grade,electronic grade and pharma grade.We also sell the pharma raw material GBL and BDO,
we have the 2 pyrrolidone production line,the capacity is 9000MT/year,according the market volume.Alpha pyrrolidone is as stong solvent and intermediate in pharma,indsutrial and electronic,it's a high quality Synthesis in NVP(n vinylpyrrolidone)etc.
Lithium batteries require very high purity of organic solvents, especially water, and their water content needs to be less than 0.02% or even lower. At present, the content of water in domestic NMP is generally greater than 0.03%. After the imported NMP is purified, its index requirements are: the chroma requirement is less than 10, the purity requirement is greater than 99.9%, and the moisture content requirement is not more than 0.02%. At present, there is less literature on the relevant purification aspects in China, and the purification research of NMP needs to be further strengthened.
