...first airship crossing of the Atlantic came in 1919 when the British R34 (using hydrogen instead of coal gas) took 4½ days to fly from the Firth of Forth to Mineola, Long Island...

...mother. This week the Minnesota Mining and Manufacturing Co. announced that its plant at Hastings, Minn, is turning out a whole litter of "fluorochemicals"-compounds just like ordinary organic chemicals (e.g., acetic acid, ether, etc.), except that they have fluorine in their molecules instead of hydrogen. It should be possible, says Dr. Nelson W. Taylor, manager of Minnesota Mining's fluorochemical department, to make fluorochemical substitutes for all the 100,000-odd organic compounds, from TNT to DDT, that chemists have synthesized...
Snug Atoms. Organic chemistry deals with carbon compounds like those found in living organisms. Most of them have long chains or rings of carbon atoms with one atom or more of hydrogen attached to each carbon atom. Fluorine atoms are heavier than hydrogen, but they are about the same size, and they fit snugly into the molecule without disturbing the existing arrangement of the carbon atoms. The result of replacing the hydrogen atoms in the molecule with fluorine is a compound which resembles the organic original in some respects. But the new fluorochemical has different and sometimes remarkable properties...
...Fluorochemicals are nobody's monopoly, but Minnesota Mining believes it has the best commercial method of making them. Instead of starting with dangerous and expensive fluorine gas, its process, invented during World War II by Professor J. H. Simons of Florida University, uses an electrolytic cell charged with hydrogen fluoride, which is much easier to handle. The organic compound that is to be transformed is mixed with the hydrogen fluoride. When an electric current is passed through the solution, fluorine atoms obediently change places with hydrogen atoms in the organic compound, turning it into the corresponding fluorochemical...
