As for イサト acid anhydride (イサト Isatoic anhydride to be, and to hit which it is sultry), a chemical formula is heterocycle of C8H5NO3.
I react chloroformic acid ethyl to benz isoxazole or anthranilic acid or am provided by reacting carbon oxychloride to anthranilic acid sodium. It becomes 板状晶 when I let you recrystallize with 柱状晶, acetone when you let you recrystallize with ethanol or acetic acid. I disintegrate at 230-253 degrees Celsius and do not show a clear melting point. I dissolve in acetone, but am hard to dissolve in alcohol. Benzene、Chloroform、Etherには does not melt.
I form salt when I react with a base and reproduce raw materials when I let carbon dioxide go through. In addition, イサト acid salt is provided when a glut uses a base. I disintegrate to anthranilic acid and carbon dioxide without becoming the イサト acid when I add acid to this.
