Title: Denise Hartnett Broughton: Innovator in Cellulose Ethers
Introduction
Denise Hartnett Broughton is a notable inventor based in Lakeland, TN (US). She has made significant contributions to the field of cellulose ethers, holding 2 patents that showcase her innovative approach to material science.
Latest Patents
One of her latest patents focuses on the preparation of cellulose ethers and the methods involved. The invention reveals that the solution rheology of cellulose ethers, particularly carboxymethyl cellulose (CMC), is enhanced when using mercerized and recovered cellulose pulp. This method involves obtaining mercerized cellulose pulp and converting it into cellulose ethers, resulting in a solution viscosity that is significantly greater than that produced from non-mercerized cellulose pulp. The mercerized cellulose pulp is typically free of cellulose III and has a higher percentage of crystalline cellulose II. Additionally, her patent outlines a method for preparing cellulose floc, which demonstrates improved bulk density compared to floc made from non-mercerized cellulose pulp.
