摘要
探索用光催化氧化木质素以制取香兰素的方法,研究了反应时间、催化剂用量、反应温度等因素对香兰素得率的影响,发现香兰素的得率随此三因素均有先增加后降低的趋势,即具有一个最佳点。
The method was developed to prepare vanillin by photocatalytic oxidation of lignin on nano-semiconductor. Influences are investigated on preparation of vanillin by this method, of reaction time, dosage of catalyst and reaction temperature. Production of vanillin increases with these factors at beginning, and then decreases after a maximum.
