PROCESS FOR THE PRODUCTION OF PHTHALIMIDES

摘要

The invention relates to a process to produce phthalimides by heating diammonium phthalate in the presence of aromatic solvents and to a process to produce phthalimides by heating diammonium phthalate in the presence of aromatic solvents for their recycled use during the on exchanger production process. The diammonium phthalate is prepared by making use of the phthalic add salts solution resulted from the on exchanger production process.
