Using menadione sodium bisulfite ( MSB) and nicotinamide as raw materials, effects of reaction conditions on synthesis of menadione nicotinamide bisulfite ( MNB) at room temperature were investigated. 以亚硫酸氢钠甲萘醌(MSB)和烟酰胺为原料,在常温下合成了稳定型维生素K3(MNB)并对影响反应的因素进行了考察。
The method was based on the reaction of the vitamin K_3 ( menadione sodium bisulfite) or menadione with thiosemicarbazide to form an violet compound in alkaline medium. 本文基于维生素K3(亚硫酸氢钠甲萘醌)或甲萘醌在碱性介质中与氨基硫脲生成紫色化合物的反应。
