高质量标准化数据集匮乏是制约催化反应机器学习和建模的主要障碍。以5-羟甲基糠醛(5-Hydroxymethylfurfural
HMF)的制备为目标,首先借助大语言模型的文本处理能力开展了大规模、选择性的文献数据提取;然后结合机器学习进行反应原料、溶剂及相关催化剂的筛选;并在机器学习的指导下有针对性地制备了具有多级孔结构的有机聚合物固体酸(

DMSO)为溶剂、155℃下反应2h后,HMF产率提升至92.8%,HMF的时空产率最高可达45.6 g-HMF/g-cat/h。本研究提出的方法有助于推动机器学习在HMF制备及催化剂研制领域的发展与应用。
The scarcity of high-quality standardized datasets is a major obstacle constraining machine learning and modeling in catalytic reactions. This study focuses on the preparation of HMF(5-hydroxymethylfurfural
HMF) via machine learning. First
leveraging the text-processing capabilities of large language models
large-scale and selective extraction of literature data was conducted. Subsequently
machine learning was employed to screen the raw materials
solvents
and related catalysts for HMF production. Based on the machine learning results
a hierarchically porous organic polymer solid acid catalyst (

artificial intelligence-assisted optimization of the reaction process conditions was carried out to enhance the yield of HMF. The machine learning results indicate that fructose as the raw material yields the highest average HMF production
indicating that it has a distinct advantage in yield-oriented HMF preparation. Using sulfonic acid-based solid acid catalysts and pure water as the solvent
the yield of HMF can reach 70.0%
while the introduction of organic solvents can increase the HMF yield to 79.2%. After machine learning-guided optimization and experimental validation
it was found that under the action of the self-prepared hSPBCH catalyst
using fructose as the raw material and dimethyl sulfoxide (DMSO) as the solvent
the yield of HMF w
as increased to 92.8% at 155°C
with the highest space-time yield of HMF reaching 45.6 g-HMF/g-cat/h. The methodology proposed in this study can contribute to promoting the development and application of machine learning in the field of HMF preparation and catalytic reactions.
