Abstract

See full text

Methods of fractionating lignocellulosic biomass using hydrotropic sulfonic acids are provided. Also provided are methods of forming lignin particles, furans, sugars, and/or lignocellulosic micro- and nanofibrils from the liquid and solid fractions produced by fractionation process. The fractionation can be carried out at low temperatures with short reaction times.
