Title: Innovations by James E. Davis

Introduction

James E. Davis is an accomplished inventor based in Hanahan, SC (US). He holds 2 patents that showcase his contributions to the field of chemical compositions. His work primarily focuses on the production and application of lignin amine salts derived from the by-products of kraft pulping processes.

Latest Patents

One of his latest patents involves the production of sulfomethylated lignin amine salts. This method utilizes the lignin by-product from black liquor residue, which is a significant aspect of the kraft pulping process. The process begins with the precipitation of lignin from the black liquor, followed by a reaction with formaldehyde. The resulting lignin slurry is then acidified to a pH of about 2 to 3 and water-washed to eliminate inorganic salts and impurities. The final product is a lignin amine salt that can be used as an additive in dyestuff and printing ink compositions, as well as a sequestrant in pesticide formulations. This innovation demonstrates improved results compared to previous lignin salts used in similar applications.
