Title: Mark W Meszaros: Innovator in Aromatic Transformation Processes
Introduction
Mark W Meszaros is a notable inventor based in Batavia, IL (US). He has made significant contributions to the field of chemistry, particularly in the area of aromatic transformation processes. With a total of 4 patents to his name, Meszaros has developed innovative methods that enhance the synthesis of various chemical compounds.
Latest Patents
One of his latest patents involves an aromatic transformation process that provides a method for transaralkylating a class of starting compounds. This process allows for the production of derivatives where benzyl substituents have different alkyl substituents compared to the starting compounds. The method is carried out by admixing the starting compound with a lower alkyl-substituted aromatic compound under liquid phase conditions, utilizing a Friedel-Crafts catalyst. This innovative approach opens new and economical routes for synthesizing lower alkyl-substituted benzyl group containing compounds, such as 2,2-di(lower alkyl-substituted) phenyl propanes and 1,3,3-trimethyl-1-(lower alkyl-substituted)-phenyl indans.
Another significant patent by Meszaros details a regioselective process for preparing 4-bromo-o-xylene. This method combines a molar excess of bromine with o-xylene, resulting in a product isomer mixture that can achieve a weight ratio of 4-bromo-o-xylene to 3-bromo-o-xylene as high as about 97:3. The process avoids concurrent production of alpha-bromo-o-xylene by conducting the reaction in darkness or in sulfur dioxide solution, allowing for easier separation of dibromo-o-xylene by-products through vacuum distillation.
