maximum absorption of hexane and heptane exists at 1500 A*.
Although there are no available data for the absorption of
ultraviolet light by isopentane, on# might expect from th*
preceding information that its maximum absorption weald be
about 1300 A. Sine* the isopentane apparently dot* not ab-
sorb in the region of 2536 R, an agent which will abtorb the
radiant energy of 3336 R and pas* it along to the hydrocarbons
will be necessary. Mercury vapor may be used for this
purpose as it absorbs radiations of 2536 R effectively in
thin layers .
Investigation of a possible reaction between mixture*
of Isobutane and isobutene sensitized by means of mercury
vapor exposed to mercury radiation of 2536 R were carried
out by Gary^, Rehrer^, and Oliver*. Stalling* investigated
th* possibility of a photo-chemical reaction of iaobutan*
