        Development of the Synol process by I. G. Farbenindustrie is reported in detail.  The process involves the direct synthesis of higher alcohols from CO and H2 over a sintered Fe catalyst specially reduced by dry, pure H2 at about 450 over a period of 50 hr. and medium pressure.  The synthesis operation is performed at about 25 atm. and a temperature of 190-225.  By raising the temperature, the same catalyst will produce a gasoline of 40-60% olefins with 65-75 octane number.  With higher pressure, Fe carbonyl formation is considerable.  The products consist almost wholly of straight-chain terminal alcohols, useful for making lubricating oils and detergents.  Methods of separating the products are discussed at some length.
