At what process conditions (T and NaOH conc) does alkaline treatment using sodium hydroxide begin to cause delignification to most biomass substances?

25 January 2017 1 5K Report

Alkaline treatment first hydrolyzes hemicellulose, but an increase in T and NaOH conc affects both lignin and cellulose. So I would like to find out the T and NaOH conc it begins and how to estimate such conditions.
