     The successful burning of heavy  fuel in gas turbines depends on the additive to prevent hot corrosion of hot gas path components, to prevent vanadium hot corrosion in the turbine hot gas path, a minimum ratio of magnesium to vanadium is required. In this work a number of oil-soluble and oil dispersible inhibitors were prepared to give a variety of magnesium complexes of different metal content and oil – solubility, these include;

      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.
