Latest Patents

Hawron's latest patents focus on a novel process for preparing bis(ether anhydrides) using alkylamine-derived compounds. This innovative process employs alkylamines with low melting temperatures, which allows for unique intermediate steps in the preparation of bis(ether anhydrides). The alkylamines utilized contain alkyl groups with at least three carbon atoms and boiling temperatures ranging from 48 to 250 degrees Celsius at atmospheric pressure. By using these amines, liquid alkylamines can now be incorporated into the imidization process step. The N-alkyl nitrophthalimides produced from the recovered imidization product can be purified through liquid/liquid extraction or vacuum distillation. This advancement enables displacement reactions to be conducted at a higher solids level, achieving greater efficiency than conventional methods.
