摘　　要：研究了一种以草酸二乙酯、异丁醛和甲醛为原料合成酮基泛内酯,再通过催化加氢合成α-羟基-β,β-二甲基-γ-丁内酯的清洁工艺,并用核磁共振、红外及色质联用对产品的结构进行了表征。The new synthesis process of α - bydray-bbbbbb, β-dimethyl-γ- butyrolactone was researched, whieh employed diethyl oxalate, isobutylaldehyde and formaldelyde as raw materials. The pi'ocess included synthesis of ketopantolac-tone and catalytic hydrogenation of ketopantolactone. Finally, the structure of the product was proved by NMR.IR and GC - MS.
