| Abstract: | The synthesis and purification of Alpha-Naphtholphthalein was studied~ With naphthol and phthalic anhydride as starting materials, the reaction conditions, including reaction temperature and time in different reaction steps were researched. Methane-sulfonic acid was selected as condensing agent. An ideal post processing method is established through the experi- ments. The chemical structure of the target compound was confirmed by IR and 1H-NMR. The purity and yield of the products were remarkably improved. |
