  6. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  7. Pyrrole - Wikipedia

    en.wikipedia.org/wiki/Pyrrole

    [22] [23] The product is a pyrrole with substituents at the 3 and 4 positions. The aldehyde reacts with the diamine to an intermediate di-imine (R−C=N−N=C−R). In the second step, a [3,3]-sigmatropic rearrangement takes place between. Addition of hydrochloric acid leads to ring closure and loss of ammonia to form the pyrrole.
