A new technique (swelling-solvation process) for the total utilization of lignocellulosics has been proposed. This process is due to a combination of the swelling of carbohydrates by concentrated acid and the solvation of lignin with phenol derivatives. The separation of wood into lignin and carbohydrates proceeds almost quantitatively at room temperature within 20 min, independent of species. The resulting lignin has several distinctive properties which conventional lignins do not have. For example, it is highly phenolic and scarcely has conjugated systems, showing a white color. On the other hand, the carbohydrates separated can easily be converted to monosaccharides in the same reaction system. This process would be applicable for any kind of phytomass to give perfect separation because of the decomposition of tissue structures during the treatment.
リグノセルロース系バイオマス成分の完全分離と構造変換のための新しいプロセス（膨潤－溶媒和プロセス）を提案した。本手法はフェノール誘導体によるリグニンの溶媒和と濃酸による炭水化物の膨潤・溶解のコンビネーションに基づいており，リグノセルロース系接合体のリグニンおよび炭水化物への分離は室温，20分でほぼ達成される。分離課程でリグニンは高機能リグノフェノール誘導体へと変換され，一方炭水化物は，分離後同一反応系で直接モノマーへと誘導可能である。
