英文
leachate control-
The method of concentrating the decoloration solution of tylosin is usually carried out by thin film vacuum concentration. in this experiment, the concentration process is modified by using the nanofiltration membrane technique which is free from corrosive due to the extractant solvent and in the same time, heating and decomposition of the antibiotic are eliminated, the concentration course ia also distinctly shortened. in this process the small molecule can be filtered by water, and the quality of the product such as, the tyramine content, the solubility of the product, improved significantly. in addition, the membrane filtration process could save consumption of steam and cooling water
泰樂星提煉過程中原工藝脫色液用薄膜真空濃縮，本試驗改進為耐溶媒納濾膜濃縮，料液不需要加熱即可濃縮，防止了料液的高溫分解破壞，濃縮收率明顯提高在濃縮的同時，部分小分子雜質可以隨水分子一起通過納濾膜而除掉，成品質量明顯提高，解決了用原工藝成品酪胺、溶解度不合格的質量問題省去了原工藝濃縮中費用較高的蒸汽、冰鹽水，經濟效益可觀。At the same time an apparatus of zone melting is designed, the method of zone melting is used to purify the purified product of recrystalizing. after purification, the homogeneity and stability of the purified product of antioxidant d and bht are examined by high performance liquid chromatography ( hplc )
