说明

General description

Potassium fluoride (KF) on activated alumina is a highly reactive catalyst (basic in nature) for various organic reactions. High reactivity is due to the formation of potassium hexafluoroaluminiate, potassium hydroxide and potassium aluminate on the interaction of its fluoride ion with alumina. Celite coated with potassium fluoride participates in various hydrogen-bond-mediated reactions. Potassium fluoride on basic alumina in acetonitrile has been employed for the ultrasound-assisted deprotection of tert-butyldimethylsilyl ethers of phenols. Neutralization reaction of hydrofluoric acid with KOH or postassium carbonate affords KF.

Application

用于研究两性聚合物凝胶的离子特异性溶胀和去溶胀的多功能氟离子源。贵金属在氟化氢中的室温氧化, 以及碱金属卤化物聚合物中离子的电子极化率的测量。
