Abstract: The present invention provides a process for the preparation of conductive polymer dispersion. In the present invention the polymer is dispersed after its synthesis, hence dispersion contains only pure poly aniline salt and stabilizer. It therefore provides a pure poly aniline dispersion without any other contamination. More particularly, the purity of the dispersed poly aniline is achieved up 99% of initiator residue and monomer residue in the present invention. The present process provides a poly aniline dispersion in water, organic solvents and also in a mixture of solvents.

Abstract: The present invention relates to a process for preparation of cinnamates using polyaniline salts as catalysts. The present invention more particularly relates to a process for producing cinnamic esters by the direct esterification of cinnamic acid with aliphatic alcohols over polyaniline salts as catalysts. The process of esterification may be carried out by reacting cinnamic acid with aliphatic mono hydric alcohol in presence of catalyst, removing the catalyst by conventional methods. The ester can be isolated such as filtration followed by isolation of esters by conventional column chromatography using adsorbent such as silica gel and solvent such as chloroform, ethylacetate, hexane and mixture there off.

Abstract: The present invention provides a process for preparing polyaniline salt using an organic acid by polymerizing an aromatic amine in presence of a mixture of aqueous and an organic solvent using an anionic surfactant and a radical initiator at a temperature in the range of 5 to 55° C. for a period ranging from 4 to 24 hours and separating it to obtain polyaniline salt in both solution and solid forms, which are soluble in organic solvents and a mixture of solvents.

Abstract: The present invention provides a process for transesterification of ketoester using polyaniline salt as catalyst, said process comprising reacting a keto ester with an alcohol in presence of a catalyst at a temperature range of 50 to 120° C. for a period in the range of 4 to 24 hours and separating the esters from the reaction mixture.
