      This work involves synthesis of different five and six member heterocyclic rings starting from acid hydrazides (m-methyl     benzoyl hydrazide and p-nitro benzoyl hydrazide) which were synthesized from their carboxylic acids.

       This work is divided into four different parts:

First part:

The aim of the present work is the synthesis of new derivatives of N-substituted diphenyl amine.The Scheme of our work involves Synthesis of different five; six and seven heterocyclic rings starting from diphenyl amine.

First part:

Spectrochemical methodswas employed for determination of wear metals (Fe, Cu, Pb and Al) that result from the internal friction between engine's component after using for a different distances in commercial fuchs lubricating oil. The samples were collected from the engine after running for 0 till 3000Km.
