Title: Michael W. Schoenherr: Innovator in Lignin Solutions
Introduction
Michael W. Schoenherr is a notable inventor based in Wausau, Wisconsin. He has made significant contributions to the field of lignin solutions, focusing on innovative methods that enhance the utility of lignin in various applications. With a total of 2 patents, Schoenherr's work is paving the way for advancements in wood bonding adhesives and phenol extenders.
Latest Patents
Schoenherr's latest patents include the development of high solids, low viscosity lignin solutions. These lignin concentrate solutions contain at least about 40% total solids and have viscosities not exceeding 10,000 cps at 25 degrees Celsius. The solutions comprise normally water-insoluble and phenol-insoluble Kraft lignin dissolved in solvents such as phenol and water or phenol-water-sodium hydroxide or ammonia. The concentrates are designed to be storable and suitable for shipment, making them ideal for use as phenol extenders in applications that typically utilize phenols. They are particularly effective in replacing 25% to 100% of the phenol component in the production of phenol/formaldehyde resins, resulting in phenol-lignin-formaldehyde (PLF) resins that are beneficial for plywood adhesives.
Another significant patent involves the creation of novel lignin-phenol-formaldehyde resins. This two-step method includes reacting formaldehyde and phenol in the presence of an alkaline catalyst to produce a partially condensed phenol-formaldehyde resin. This precondensed resin is then reacted with sodium hydroxide, formaldehyde, and a lignin concentrate, which has at least 40% solids. The method is designed to control the degree of condensation, ensuring the production of effective wood bonding adhesives.
