摘要

The fairly ignored (1R,5S)-anhydroisosaccharino-δ-lactone (LAC) is a compound formed at significant levels from catalytic pyrolysis of cellulose [1] and lignocellulosic biomass.[2] Recently LAC production in a gram scale by cellulose pyrolysis was upgraded.[3] Isolation and purification procedures were improved and its presence in bio-oils quantitatively evaluated by a fast and efficient FT-IR method, previously validated by ~1HNMR analysis. The best results were obtained at 500°C by mesoporous Sn-MCM-41 catalyst (7.6% yield from cellulose, 6.6% after a regeneration cycle) and by the cheap and eco-friendly montmorillonite K10 (4.8%).
