Has a prominent contribution to the national economic development in the chemical industry , fine chemicals, organic synthesis as a core technology . The acid catalyst in organic synthesis are also plays a particularly important role , currently used an acid catalyst with a liquid acid catalyst , solid acid catalyst, etc. . Acid doped polyaniline having a characteristic, which may be inorganic acid such as hydrochloric acid , sulfuric acid , benzenesulfonic acid , p-toluenesulfonic acid , and organic acids such as to carry out doping , and thus shows good catalytic properties in organic conversion . The papers of acid doped polyaniline catalyst catalytic performance do the following aspects : 1 . Target reaction , turpentine hydration effects of acid doped type , acid concentration , aniline and persulfate molar ratio preparation conditions on the catalytic properties of polyaniline catalyst obtained the better acid doped polyaniline catalyst preparation conditions . 2. In acid the doped polyaniline catalytic system conditions , turpentine hydration reaction conditions were investigated , and turpentine hydration reaction kinetic analysis to establish the corresponding kinetic equations . Α-pinene isomerization reaction and acetic acid , n-butanol esterification reaction examined the catalytic properties of doped polyaniline catalyst . SEM, IR, BET, XRD analysis test were characterized by means of the acid doped polyaniline activity of the catalyst composition, morphology , surface area , and associated with the catalytic activity of the catalyst .
