Title: Gerd Collin: Innovator in Carbon Fiber and Naphthalene Production
Introduction
Gerd Collin is a prominent inventor based in Duisburg, Germany, known for his significant contributions to the fields of carbon fiber production and chemical processes. With a total of 12 patents to his name, Collin has made remarkable advancements that have implications for various industries.
Latest Patents
Among his latest innovations is a novel spinning method for producing carbon fibers from high boiling bituminous substances. This process involves spinning a purified and polymerized concentrated carbon fiber precursor into fibers, which are then oxidized and carbonized. A key improvement in this method is the addition of 2 to 10% by weight of a solvent, which is insoluble or only slightly soluble under normal conditions, just before spinning. This mixture is then processed under hypercritical conditions for at least 10 minutes, ensuring that no gas or solid inclusions form in the fiber, thus preventing the neoformation of solids.
Another notable patent by Collin is the preparation of 2,6-dialkyl-naphthalenes. This process selectively alkylates naphthalene or 2-alkyl-naphthalene with an alkylating agent in the presence of a zeolite catalyst at temperatures ranging from 250°C to 345°C. The resulting dialkyl-naphthalenes are valuable for producing naphthalene 2,6-dicarboxylic acid, which is essential for creating high-quality polyesters or polyamides.
