摘要:
以全氟丁基磺酰氟、2,2,3,3-四氟丙醇和2,2,3,3,4,4,4-七氟丁醇为原料,经酯化和醚化两步反应合成了2,2,3,3-四氟丙基-2,2,3,3,4,4,4-七氟丁基醚. 考察了两步反应投料比、反应温度和反应时间等条件对产物收率的影响. 实验结果表明,酯化反应在反应温度25 ℃,全氟丁基磺酰氟、四氟丙醇、氢氧化钾摩尔投料比为1∶3∶1.3条件下反应时间16 h最佳,中间产物全氟丁基磺酸2,2,3,3-四氟丙酯收率达92.3%;醚化反应在75 ℃下反应18 h,中间产物磺酸酯、七氟丁醇、碳酸钾摩尔投料比为1∶1.2∶0.6条件下最优,得到2,2,3,3-四氟丙基-2,2,3,3,4,4,4-七氟丁基醚,产物总收率86.9%,纯度98.6%以上,其结构经核磁共振氢谱、碳谱和氟谱表征确认.
Abstract:
The 2,2,3,3-tetrafluoropropyl 2,2,3,3,4,4,4-heptafluorobutyl ether was synthesized through two reactions of esterification and etherification, using nonfluorobutanesulfonyl fluoride,2,2,3,3-tetrafluoro-1-propanol and 2,2,3,3,4,4,4-heptafluoro-1-butanol as the raw materials. The effects of proportion of reactant, temperature and time of reaction on the yield of product were investigated. The yield of 2,2,3,3-tetrafluoropropyl nonafluoro-1-butanesulfonate reaches 92.3% at the molar ratio of nonfluorobutanesulfonyl fluoride, 2,2,3,3-tetrafluoro-1-propanol to 2,2,3,3,4,4,4-Heptafluoro-1-butanol of 1∶3∶1.3, reaction time of 16 h and reaction temperature of 25 ℃. The yield of 2,2,3,3-tetrafluoropropyl 2,2,3,3,4,4,4-hepta-fluorobutyl ether is 86.4% with purity more than 98.6% at the molar ratio of intermediate, 2,2,3,3,4,4,4-heptafluorobutyl ether to potash of 1∶1.2∶0.6, reaction time of 18 h and reaction temperature of 75 ℃. The structure of the product was confirmed by nuclear magnetic resonance hydrogen spectrum, nuclear magnetic resonance carbon spectrum and nuclear magnetic resonance fluorine spectrum.
