由于市场缺货,经过一段摸索过程,我们由苯巴比妥制成了苯巴比妥钠。我们采用的方法与徐继斌介绍的方法基本相同,但不经过浓缩直接制成符合药典规格的苯巴比妥纳结晶,方法简便,产量较高,适合于药房少量制备。现将我们的经验介绍如下。苯巴比妥钠的制造是利用等分子量的苯巴比妥与氢氧化钠或碳酸钠相作用而成。 Due to the shortage of the market, after a groping process, we made phenobarbital sodium phenobarbital. The method we used is basically the same as that introduced by Xu Jibin, but it can be directly prepared into phenobarbital crystals in compliance with Pharmacopoeia specifications without any concentration. The method is simple and has high yield and is suitable for small quantity preparation in pharmacies. Now we introduce the experience below. The manufacture of phenobarbital is the use of equal molecular weight phenobarbital with sodium hydroxide or sodium carbonate phase from the role.
