                 摘要:以八氟戊醇和 2,3-二溴丙醇为原料,设计并合成了甘油醚类氟碳表面活性剂(2,3-双八氟戊烷氧基-1-硫酸

                 丙酯钠,BOFPGS),通过 FTIR、 HNMR、 FNMR 以及 MS 等对中间产物(2,3-双八氟戊烷基-1-丙醇)和最终
                 产物(BOFPGS)进行了结构表征。对 BOFPGS 进行了表面张力测试,结果表明,BOFPGS 的临界胶束浓度(CMC)
                         –3
                 为 4.16×10 mol/L,CMC 对应的表面张力为 22.70  mN/m。将不同浓度的 BOFPGS 水溶液和相同体积的液体石
                                                                                               –3
                 蜡乳化后,析水率随着时间延长而增大,乳液在乳化 30 min 时趋于稳定。BOFPGS 浓度低至 0.8×10 mol/L 时,
                 其仍具有较好的乳化性能。利用噻唑蓝(MTT)法对该表面活性剂的细胞毒性进行测试,结果表明,BOFPGS
                                   –4
                          –6
                 在 8.04 × 10 ~1.60 × 10  mol/L 浓度范围内无明显细胞毒性。

                 Abstract: A novel glyceryl ether fluorocarbon surfactant, sodium 2,3-bis[(2,2,3,3,4,4,5,5-octafluoropentyl)oxy]
                 propyl-1-sulfate (BOFPGS)  was  designed  and  synthesized  from  2,2,3,3,4,4,5,5-octafluoro-1-pentanol  and
                                                                                                  1
                 2,3-dibromopropan-1-ol. The structures of the intermediate and product were characterized by FTIR,  H and
                 19 FNMR spectroscopy and MS. The surface activity of BOFPGS was measured. The results showed that the
                                                              –3
                 critical micelle concentration of BOFPGS was 4.16×10 mol/L and the corresponding surface tension was
                 22.70 mN/m. The same volume of liquid paraffin was emulsified with different concentrations of BOFPGS
                 aqueous  solution,  respectively.  It  was  found  that  the  water  seperation  rate  increased  with  time  and  the
                 emulsion tended to be stable at 30 min. Moreover, BOFPGS possessed excellent emulsifying performance at
                       –3
                 0.8×10 mol/L. The cytotoxicity of BOFPGS was tested by MTT assay. The results showed that BOFPGS
                                                                      –4
                                                            –6
                 had no obvious cytotoxicity in the range of 8.04 × 10 ~1.60 × 10 mol/L.
