The invention provides a process for organosolv pulping, wherein solid lignocellulosic feed material is heated at a temperature in the range of fro m 50 to 210 ~C in a solvent to obtain a solid cellulosic fraction comprising a t least 50 wt% of the cellulose present in the feed material and a liquid fraction, wherein the solvent comprises at least 10 wt% of a compound according to general molecular formula (1) wherein R1 to R6 each represent, independently, a hydrogen atom or an organic group connected with a carbon atom to the lactone group. The invention further provides the use of a compound according to general molecular formula (1) in a solvent for organosolv pulping.
