Joseph J Pedjac is a notable inventor based in Mount Pleasant, MI (US). He has made significant contributions to the field of chemistry, particularly in the development of bromination processes. With a total of 2 patents, his work has advanced the production of high-purity brominated compounds.

Latest Patents

Pedjac's latest patents include a bromination process that prepares high-purity perbrominated aromatic compounds, especially decabromodiphenyl oxide. This process involves adding an aromatic compound to a mixture comprising an organic solvent, a catalyst, and a slight stoichiometric excess of bromine, all at a low initial reaction temperature. Another significant patent is for the preparation of brominated pentaerythritols. In this process, brominated pentaerythritols are prepared at reaction temperatures ranging from about 85°C to 135°C by reacting pentaerythritol with HBr in the liquid phase. This method employs a solvent medium containing from about 0.8 to about 25 mole percent of an aliphatic carboxylic acid of 2 to 8 carbon atoms and their anhydrides, based on the pentaerythritol. The HBr is continuously fed to the reactor throughout the reaction, and the water formed remains in the reaction mixture until substantial completion.
