WHY BF, IS THE CATALYST TO THINK OF FIRST Does a universal catalyst exist? Boron Trifluoride — a major development of General Chemicars fluorine research program—seems to be the next thing to it! In a broad spectrum of reactions, it speeds reaction rates, increases yields, lowers costs, refines through-put—in acylation, alleviation, arylation, condensation, cyclization,esterification,halogenation, hydration, isomerization, nitration, and many others. For

any new organic synthesis process, it has become standard practice to try a BFs catalyst first. General Chemical offers BF3 gas and a wide selection of BF3 complexes, in one-pound laboratory quantities right through to tank car lots. Its development from a laboratory curiosity to a workhorse catalyst is but one example of the way General Chemical research has advanced fluorine technology . . . contribut-
