研究了伯胺N192 3 萃取剂对螺旋霉素和红霉素的萃取性能 ,实验结果表明它具有萃取率高、适用 pH范围较大、不乳化、易分相、易反萃、用量小且可多次循环使用等优点 ,显示出了作为工业萃取剂的良好特性。适宜的萃取条件分别为对螺旋霉素用 5 0 %N192 3,pH=9.56,O/A =1∶1(V/V) ,萃取率为 90 8% ;萃取红霉素用 7 5%N192 3,pH =9.50 ,O/A =1∶1,萃取率为 92 %。 The extraction performance of spirithin and erythromycin from primary amine N192 3 was studied. The experimental results show that it has the advantages of high extraction rate, high pH range, no emulsification, easy phase separation, easy stripping, small dosage and The advantages of multiple cycles, etc., show good properties as an industrial extractant. The optimum extraction conditions were as follows: 50% N192 3, pH = 9.56, O / A = 1: 1 (V / V) for spiramycin, 90 8% 3, pH = 9.50, O / A = 1: 1, the extraction rate was 92%.
