Method for preparing rod-like bisphenol A type diether diphthalimide

The invention relates to a method for preparing rod-like bisphenol A type diether diphthalimide. The method comprises the following steps: (A) enabling bisphenol A to react with a strong base in a nonpolar solvent so as to prepare a bisphenol A salt; (B) conducting a nucleophilic reaction on the bisphenol A salt with phthalimide in a polar aprotic solvent; and (C) separating a reaction liquid froma hot alcohol type solvent with an additive, conducting filtration so as to obtain a crude product filter cake of diether diphthalimide, conducting heating backflow on the filter cake in an alcohol solvent for multiple times, and conducting filtration and drying, so as to obtain the rod-like bisphenol A type diether diphthalimide with high purity. By adopting the method, the problems that in a conventional production technique, diether diphthalimide is liable to cake and aggregate when being separated, and crystal granules are small and hard to filter, can be solved, a rod-like product of good dispersibility and large granules is prepared, the filtration efficiency is greatly improved, and in addition, the obtained rod-like bisphenol A type diether diphthalimide is high in purity and convenient in downstream use.

Preparation method of low-yellowness diether diphthalimide

The invention relates to a preparation method of low-yellowness diether diphthalimide. The method comprises the following steps: (A) performing a reaction on diphenol with strong alkali in a non-polarsolvent to prepare diphenol salt; (B) carrying out a nucleophilic reaction on the product obtained in the step A and phthalimide in a polar aprotic solvent; and (C) after the reaction in the step (B)is finished, introducing chloromethane and/or chloroethane gas into the system to prepare the diether diphthalimide. By adopting chloromethane and/or chloroethane gas to react with residual phenolichydroxyl/phenolate end groups to generate stable alkyl, the method solves the problems that a diether diphthalimide product is yellowed in color and is easy to oxidize and yellow in the existing production technology process.

METHODS FOR THE MANUFACTURE OF AN AROMATIC BISIMIDE AND A POLYETHERIMIDE

A method for producing an aromatic bisimide includes reacting a dialkali metal salt of a dihydroxy aromatic compound with an N-alkyl nitrophthalimide to form a product mixture including the aromatic bisimide. The N-alkyl nitrophthalimide includes 4-nitro-N-(C1-13 alkyl)phthalimide, 3-nitro-N-(C1-13 alkyl)phthalimide, or a combination including at least one of the foregoing, and 4-hydroxy-3,5-dinitro-N-(C1-13 alkyl)phthalimide in an amount of 1-10000 ppm. The aromatic bisimide can be obtained in a yield of greater than 75%, or 90-99.8%. A method for the manufacture of a polyetherimide, a polyetherimide, and an article including the polyetherimide are also disclosed. A mixed acid nitration process for the preparation of an N-alkyl nitrophthalimide is also described.
