D-Pantothenyl alcohol, also called ortho-vitamin 85, is an important nutrition suppled substance. It has been widely applied in the field such as medicine, cosmetic, foodstuff, feed additive, and so on. The preparation of D-pantothenyl alcohol and the optimization of key factor are discussed mainly in this paper. It mainly includes three section.In the first section, with formaldehyde, isobutyl aldehyde and diethyl oxalate as the starting materials, D-pantolactone is prepared via three steps including condensation, catalytic hydrogenation and physical resolution. The specific rotatory power of the product is consistent with imported product.

D-泛醇，俗称原维生素B_5，属维生素B旋类营养增补剂，广泛应用于医药、化妆品、食品、饲料等领域，本文着重探讨了其制备及关键因素的优化，主要内容可分三部分：第一是D-泛内酯的制备，先以甲醛、异丁醛和草酸二乙酯为起始原料合成酮基泛内酯，再经催化氢化得到DL-泛内酯，然后通过物理拆分获得D-泛内酯，得到产物的比旋光度与进口产品基本一致。
