  • Phosphorylated lignocellulosic fibers, uses and processes of preparation thereof
    Patent number: 11021577
    Abstract: The present disclosure relates to lignocellulosic materials comprising phosphorylated lignocellulosic fibers having an ionic charge in water of about 4000 to about 7000 mmoles/kg, and processes for the preparation thereof. The process comprises reacting lignocellulosic fibers of a lignocellulosic material with a phosphate ester in the presence of urea. The present disclosure further relates to compositions comprising a phosphate ester and at least one of a defoamer and a viscosity reducer or at least one of a C1-C12 alcohol and an ester of a carboxylic acid.
    Type: Grant
    Filed: June 12, 2017
    Date of Patent: June 1, 2021
