A satisfactory process for the preparation of p-iodo- and 2,4-diiodo-aniline has been developed, aniline being treated with iodine in the presence of mercuric oxide. Acetanilide was also iodinated by this procedure. When lead, calcium, and ferric oxides were employed the yields of p-iodo-aniline proved to be only slightly greater than that obtained by the action of iodine alone, whilst zinc oxide lowered the yield considerably. The influence of added iodides, acids, and mercuric iodide on the rate of reaction of iodine and aniline was investigated. A theory has been proposed to explain the role of mercuric oxide in effecting the iodination of aniline.

Potential Applications

Zinc oxide has been the focus of material research due to its potential applications in a variety of novel fields. The material exhibits anisotropic growth in the form of single crystal rods/wires of length in microns and thickness in several tens of nanometers through a facile and low temperature hydrothermal route wherein size, morphology, orientation, and growth rate are strongly dependent on a number of synthesis parameters. In this review article we intend to present/discuss the effects of important growth parameters of zinc oxide that have been reported in the literature. These parameters include concentration of the precursor solution, growth time, role of hexamine, synthesis temperature, pH of the precursor, and seeding layer deposited on a substrate.
