P R O B L E M : A n effective solid catalyst was s o u g h t f o r the alkylation o f isobutane w i t h ethylene t o produce diisopropyl, a high octane gasoline conn* ponent valuable f o r its high lead susceptibility and excellent volatility.
S O L U T I O N : Use o f BF 3 with certain hydrated salts produces active alkylation catalysts which bypass many problems encountered w i t h known catalysts. These new catalysts can be used a t low temperatures—thus avoiding undesirable side reactions and m i x i n g problems due t o changes i n viscosity.
NEED A BETTER CATALYST? INVESTIGATE T h e versatility of boron trifluoride md its cost-cutting advantages make i t a catalyst to be considered in almost any organic synthesis problem. The use of BF3 a s an alkylation catalyst in the preparation of diisopropyl (described above) is an excellent recent example. T h e next synthesis problem BF3 will help solve may well be yours! H e r e are some of t h e reactions catalyzed by BF3 : polymerization, alkylation, esterification, nitration, sulfonation, halogenation, isomerization, arylation, cy clization, hydration, acylation, a n d there are m o r e !
