Abstract: | Manufacture of fatty acids from petroleum and natural gas is a large industry worldwide and has important implications in
the U.S. Eastern Europe produces an estimated 1.2 billion pounds by air oxidation of hydrocarbons compared to an estimated
956 million pounds of natural fatty acids from the U.S., in 1978 (exclusive of tall oil fatty acids). The enormous production
of SFA’s in Eastern European countries and in Russia is done by continuous air oxidation of fresh and recycled mixed aliphatic
hydrocarbons. Since the products contain proportions of odd-numbered straight chain acids, they have not been used edibly,
but have been applied to the manufacture of industrial products such as soap, lubricants, plasticizers and the like. Another
European approach (Liquichimica, Italy) for SFA is the caustic fusion (and oxidation) of branched chain alcohols produced
by carbonylation and reduction of olefins. American potential technology is diversified but has not yet been translated to
production scale, presumably because of the plentiful supply of natural fats and oils that is available. |
