本论文主要研究了以四氢糠醇为原料合成吡啶的工艺。
The process for the synthesis of pyridine using tetrahydrofurfuryl alcohol (THFA) as material was researched in this article.
四氢硼钠在己烷和甲苯溶剂中,不易引发丙烯酸第三丁酯的聚合反应,但在吡啶和四氢呋喃中能引发聚合,亦得到非晶态聚合物。
NaBH4 in hexane or toluene would not initiate the polymerization unless pyridine or THF was used as solvent, but an amorphous polymer was the product.
