补充资料:维生素K3
分子式:C11H8O2
分子量:172.18
CAS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。
