【摘要】 以八甲基环四硅氧烷、γ-氨丙基甲基二乙氧基硅烷(KH-902)、六甲基二硅氧烷和六氟丙烯三聚体等为原料,制备了一种新型氟硅化合物(HFPT-902),用红外光谱和核磁共振光谱对其进行了结构表征。考察了投料方式、反应温度、反应时间和n(氨基硅油)∶n(六氟丙烯三聚体)等因素对目标产物转化率的影响,得到最优工艺条件为:逐滴滴加六氟丙烯三聚体、反应温度70℃、反应时间3 h、n(氨基硅油)∶n(六氟丙烯三聚体)=1.0∶1.2。更多还原

【Abstract】 A new fluorosilicone compound(HFPT-902) was synthesized through a series of reaction using octamethyl cyclotetrasiloxane, 3-aminopropyl methyldiethoxy silane(KH-902), hexamethyldisiloxane and hexafluoropropylene trimer as materials. The chemical structure of HFPT-902 was characterized by FTIR and13 CNMR. The effects of feeding mode, reaction temperature, reaction time and molar ratio of amino silicone to hexafluoropropylene trimer on the yield of target product were investigated. The optimum conditions were as follow: adding hexafluoropropylene trimer drop by drop, reaction temperature was 70 ℃, reaction time 3 h, n(amino silicone oil)∶n(hexafluoropropylene trimer) 1.0∶1.2.更多还原
