COMPOSITION OF THE PETROLEUM OF THE CAUCASUS.

By MM. P SCHUTZENBERGER and N. TONINE.


All portions of this petroleum contain saturated carbides of the formula
C_nH_{2n}, which the authors name paraffenes. At a bright red heat they
yield benzinic carbides, C_nH_{2n-6}, naphthalin and a little anthracen.
At dull redness the products are along with unaltered paraffenes,
products which unite energetically with bromine, and which are converted
into resinous polymers of ordinary sulphuric acid. It is difficult to
isolate, by means of fractional distillation, definite products with
constant boiling points.
