Kinetics of lignin pyrolysis

The kinetic equation for lignin decomposition can be established in this case only for small temperature intervals ATr. For such an interval (ATr)], the following relation can be written  

181 3-(2-methyi)ethylidene-5-(2-methyl)ethyl-pyrrolidine-2,4-dione X X 

195 4-(3-methyl)propyl-2-(2-methyl)ethyl-3,4-dihydro-(2H)-pyrrole-3,5-dione X X
