Isatoic Anhydride

Description

Used in organic synthesis.

 
It is used as raw material of medicine, pesticide and dye, and is an important intermediate of herbicide bentazon.
Starchanthranilate improves retention of inorganic fillers and fine fibers, as well as dry and tensile strength in paper industry. In the presence of various solvents and various catalysts, starch o-aminobenzoic acid esters are prepared by the reaction of starch and indigo anhydride. The classical method is the reaction of triethylamine in dimethyl sulfoxide solvent as catalyst.
