Efficient Method for Pretreating Lignocellulosic Materials to Produce Paper with Improved Properties

UW-Madison researchers now have improved their previous technology by using derivatives of oxalic acid, preferably diethyloxalate (liquid) and dimethyloxalate (solid). These derivatives work better than oxalic acid in the pulping process.  They can be added to the wood chips as dry components and then treated with steam.
