harnessing Can it go to work for you ? As α versatile reaction medium, hydrofluoric acid features high activity, low boiling point, strong de­hydrating action for efficient fiuormation, nitration, suifonation, diazotization, molecular rearrangements. As s Vr'lde-rarsge soîybsuzer, H F salves knotty separa­tion problems on metals like Τ?»* C b ; 7*T. ï-tf. Te and Se . . . dissolves relatively insoluble oxides like those of Ti , Zr and Ta . . . stabilizes unusxial oxidation states of metals like Co, Mn and Ni.

As α catalyst, H F specializes in farming new carbon-to-carbon bonds. I t brings new economies to alkylation . . . is effective in polymerizing s^ich compounds as amylene, butadiene, styrene, thiophene and other

pays off materials, yielding high molecular weight products. As α reactant, H F forms many types of useful inorganic salts, including fluorides, fiuoborates, âuophosphates, double fluorides.
