Vi-tamin K3分子式：C11H8O2分子量：172.18CAS号：58-27-5性质：亮黄色晶体。熔点104-105℃。溶于乙醇、苯、氯仿、四氯化碳和植物油等，不溶于水。遇光或铁质分解变质，能随水蒸气挥发。制备方法：有两种生产工艺。1.甲基萘用铬酐氧化而得。将2-甲基萘溶解于冰醋酸中，搅拌冷却到40℃以下，缓缓加入铬酐与等量水的混和液，使温度维持在35-40℃。加毕，在40℃保温0.5h，升温到70℃保温45min，再升温到85℃保温15min，将反应物倾入大量水中，不断搅拌下沉淀出2-甲萘醌。过滤，滤饼反复用水洗，至水溶液无酸味，滤干得2-甲萘醌。收率51%。2-甲基萘也可用重铬酸钠、重铬酸钾氧化收率大致相同。2.由甲苯醌与丁二烯环合得到2-甲基萘氢醌，再经铬酸氧化而得。将甲苯醌加入冰醋酸中溶解，通入丁二烯，在20℃以下通至所需量。密闭静置20h后，加热使剩余的丁二烯逸出，继续加热至110℃左右回流3h，再减压蒸馏回收冰醋酸约30%。然后冷却至40℃以下，缓缓加入铬酸与等量水的混合液，使温度保持在65-70℃，加毕，在70-80保温1h而生成甲萘醌。用途：该品与亚硫酸氢钠加成即得维生素K3。
