Method for preparing trimellitic anhydride acid chloride through distillation and purification with film evaporator

The invention specifically relates to a method for preparing trimellitic anhydride acid chloride through distillation and purification with a film evaporator, belonging to the technical field of organic synthesis of fine chemical intermediates. The method comprises the following steps: with trimellitic anhydride and thionyl chloride as raw materials, carrying out a reflux reaction in a solvent under the action of a tri-n-butylphosphine catalyst so as to obtain a reaction solution after the reaction; subjecting the reaction solution to pressure-reduced distillation to remove the solvent and excess thionyl chloride; and then carrying out distillation, separation and purification with the film evaporator, and carrying out cooling to obtain trimellitic anhydride acid chloride. The method provided by the invention has the advantages of simple process, high product purity, recyclability of the solvent and thionyl chloride, and the like, and is suitable for industrial production.

Polyamide-imide with indan structure and preparation method of polyamide-imide

The invention provides polyamide-imide with an indan structure. The polyamide-imide has a structural formula as shown in the specification, and in the formula, n is from 1 to 8. The invention further discloses a material which is prepared after the polyamide-imide with the indan structure is cured at 220-380 DEG C, and a preparation method of the polyamide-imide with the indan structure. The invention studies the synthesis and the properties of polyamide-imide, thermal-curing polyamide-imide of different polymerization degrees is prepared from 5(6)-amino-1-(4-amino phenyl)-1,3,3-trimethyl indan as monomers, then the stacking density and the interaction of molecular chains can be reduced, the flexibility of the molecular chains can be improved, and finally polyamide-imide resin which is excellent in solubleness and excellent in thermal resistance can be synthesized.
