Title: Edgar Fuhrmann: Innovator in Hydrocarbon Resins

Introduction

Edgar Fuhrmann is a notable inventor based in Castrop-Rauxel, Germany. He has made significant contributions to the field of chemical engineering, particularly in the development of hydrocarbon resins. With a total of 5 patents to his name, Fuhrmann's work has had a considerable impact on various industrial applications.

Latest Patents

One of Fuhrmann's latest patents is focused on a hydrocarbon resin and the process for its production. This hydrocarbon resin is obtainable through the thermal polymerization of a cyclic diolefin component, which includes a cyclic diolefin compound, combined with an aromatic component that includes indene and/or C-alkylindene. The resulting hydrocarbon resin has a polydispersity index (PDI) ranging from 1 to less than 2.3. The production process involves polymerizing a monomer mixture at a temperature of at least 180° C. to yield a product stream that includes hydrocarbon resin and oligomers. These oligomers, which contain units from both the cyclic diolefin compound and the aromatic component, are separated and returned to the monomer mixture for further processing.

Another significant patent by Fuhrmann involves the selective production of o-alkylphenols. This method entails converting phenol with an alkanol at elevated temperatures in the gas phase, utilizing a metal catalyst. The process is conducted in at least two stages, with the alkanol/phenol molar ratio maintained at approximately ≤0.4 in each stage. This careful control results in a marked increase in the selectivity for the desired o-alkyl phenol.
